Pull SoC fixes from Arnd Bergmann:
"Following the previous set of fixes, this addresses another
significant number of small issues found in firmware drivers (tee,
optee, qcomtee, qcom ice, exynos acpm) drivers through various tools.
This is about error handling, resource leaks, concurrency and a
use-after-free bug.
The fixes for the Qualcomm ICE driver also introduce interface changes
in the UFS and MMC drivers using it.
Outside of firmware drivers, there are a few fixes across the tree:
- Minor driver code mistakes in the Atmel EBI memory controller, the
i.MX soc ID driver and socfpga boot logic
- A defconfig change to avoid a boot time regression on multiple
qualcomm boards
- Device tree fixes for qualcomm, at91 and gemini, addressing mostly
minor configuration mistakes"

commit 2d1f7b65f5de ("dm cache policy smq: fix missing locks in
invalidating cache blocks") added mq->lock around the destructive part of
smq_invalidate_mapping(), but left the e->allocated check outside the
critical section.
That leaves a check-then-act race. Two concurrent invalidators can both
observe e->allocated as true before either of them takes mq->lock. The
first invalidator that acquires the lock removes the entry from the
queues and hash table and then calls free_entry(), which clears
e->allocated and puts the entry back on the free list. The second
invalidator can then acquire mq->lock and continue with the stale result
of the unlocked check.
This can corrupt the SMQ queues or hash table by deleting an entry that
is no longer on those structures. It can also hit the allocation check in
free_entry() when the same entry is freed again.
Move the allocation check under mq->lock so the predicate and the
destructive operations are serialized by the same lock.

Commit eac69475b01f ("media: rc: igorplugusb: heed coherency
rules") changed the control request storage from an embedded struct to
an allocated pointer so it can obey DMA coherency rules.
However, the driver still passes &ir->request to usb_fill_control_urb().
That points the URB setup packet at the pointer field itself rather than
at the allocated struct usb_ctrlrequest.
USB core then interprets pointer bytes as the setup packet. This can
produce an invalid bRequestType and trigger the control direction warning
reported by syzbot:
usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0
Pass ir->request itself as the setup packet.
Fixes: eac69475b01f ("media: rc: igorplugusb: heed coherency rules")

virtio_i2c_probe() synchronously probes child i2c drivers on the bus,
but peripherals may use the bus at probe for tasks like reading a chip
id. The vhost-user-i2c backend stalls at such probes unless DRIVER_OK
is already set before the virtqueue is first kicked.
Set DRIVER_OK explicitly before i2c_add_adapter(), as done for the
same reason in commit f5866db64f34 ("virtio_console: enable VQs
early") and commit 71e4b8bf0482 ("virtio_rpmsg: set DRIVER_OK before
using device").

drm_gem_change_handle_ioctl leaves the old handle live in the IDR
during the window between spin_unlock(table_lock) and the final
spin_lock(table_lock). A concurrent drm_gem_handle_delete on the old
handle succeeds in this window, decrements handle_count to 0, and frees
the GEM object while the new handle's IDR entry still references it.
NULL the old handle's IDR entry before dropping table_lock so that any
concurrent GEM_CLOSE on the old handle sees NULL and returns -EINVAL.
Restore the old entry on the prime-bookkeeping error path.

With how this is currently written, we add the trailer, zero it out, and
then add the header space on. If that header space requires a
reallocation + copy, the zeros in the trailer aren't copied, because the
skb len hasn't actually been yet expanded to cover that. Instead add the
padding at the end of the process rather than at the beginning.

Sashiko identified a possible infinite loop [1].
ACPM IPC sequence numbers are tracked via a 64-bit bitmap. Previously,
acpm_prepare_xfer() used a do...while loop to search for a free
sequence number.
If all 63 available sequence numbers are leaked due to transient
hardware timeouts or mailbox failures, the bitmap becomes full.
The next call to acpm_prepare_xfer() would enter an infinite loop.
Fix this by utilizing the kernel's optimized bitmap search functions
(find_next_zero_bit / find_first_zero_bit). If the pool is completely
exhausted, log the failure and return -EBUSY to allow the kernel to
fail gracefully instead of hanging.
Furthermore, drop the allocation loop entirely. Because
acpm_prepare_xfer() is strictly called under the 'tx_lock' mutex,
sequence number allocations are perfectly serialized. If
find_next_zero_bit() locates a free bit, a single
test_and_set_bit_lock() is mathematically guaranteed to succeed.
To enforce this locking invariant, wrap the allocation in a
WARN_ON_ONCE. If the atomic set fails, it indicates the driver's
mutex serialization is fundamentally broken. The warning generates a
stack trace for debugging, while returning -EIO immediately aborts the
transfer to prevent silent payload corruption.

Sashiko identified memory ordering races in [1].
The ACPM driver uses a globally shared 'bitmap_seqnum' to track
available sequence numbers. Even though threads now strictly free their
own sequence numbers, the allocation and freeing of these bits across
concurrent threads are effectively lockless operations and require
explicit LKMM memory barriers.
Previously, the driver used plain bitwise operators (test_bit, set_bit,
clear_bit), which lack ordering guarantees. This creates two race
conditions on weakly ordered architectures like ARM64:
1. Polling Release Violation: The polling thread copies its payload and
calls clear_bit(). Without a release barrier, the CPU can reorder
the memory operations, making the cleared bit globally visible
before the payload reads have fully completed.
2. TX Acquire Violation: The TX thread loops on test_bit(), calls
set_bit(), and then wipes the payload buffer via memset(). Without
an acquire barrier, the CPU can speculatively execute the memset()
before the bit is safely and formally claimed.
If these reorderings overlap, a new TX thread can claim the sequence
number and overwrite the buffer while the original polling thread is
still actively reading from it.
Fix this by upgrading the bitwise operators. Wrap the TX allocation in
test_and_set_bit_lock() to establish formal LKMM Acquire semantics, and
pair it with clear_bit_unlock() in the polling path to enforce Release
semantics.

Sashiko identified severe races in the polling state machine [1].
In the ACPM driver's polling mode, threads waited for responses by
monitoring the globally shared 'bitmap_seqnum'. This caused false
timeouts because if a thread processed its response and freed the
sequence number, a concurrent TX thread could immediately reallocate
it before the polling thread woke up.
Additionally, the driver suffered from a cross-thread Use-After-Free
(UAF) preemption race. Previously, acpm_get_rx() cleared the sequence
number of whichever RX message it drained from the hardware queue. This
meant Thread A could globally free Thread B's sequence slot while
Thread B was asleep. A new Thread C could then steal the slot,
overwrite the buffer, and leave Thread B to wake up to corrupted state
or a timeout.
Fix this by rewriting the polling state machine:
1. Decouple polling from the global allocator by introducing a per-slot
'completed' flag, synchronized via smp_store_release() and
smp_load_acquire().
2. Strip acpm_get_saved_rx() out of acpm_get_rx() to make it a pure
queue-draining function. Introduce a 'native_match' boolean argument
which evaluates to true only if the thread natively processed its
own sequence number during the call. This explicitly informs the
polling loop whether it must retrieve its payload from the
cross-thread cache.
3. Centralize the cache fallback and sequence number free (clear_bit)
inside the polling loop. Crucially, the free operation now strictly
targets the thread's own TX sequence number (xfer->txd[0]), rather
than the drained RX sequence number. This enforces strict ownership:
a thread only ever frees its own allocated sequence slot, and only
at the exact moment it completes its poll, eliminating the UAF
window.
Furthermore, explicitly guard the 'native_match' assignment with an
if (rx_seqnum == tx_seqnum) check, even for zero-length (no payload)
responses. While an unguarded assignment wouldn't crash (because the
cache fallback acpm_get_saved_rx() safely returns early on zero-length
transfers) doing so would "lie" to the state machine. If a thread
drained the queue and found another thread's zero-length message,
setting native_match = true would falsely convince the polling loop
that it natively handled its own response. Maintaining a rigorous state
machine requires that native_match is only set when a thread explicitly
processes its own sequence number.

Fix integer overflow issues in the dumb buffer creation path:
1. drm_mode_create_dumb() does not bound width, height, or bpp
before passing them to driver callbacks. Downstream helpers
(e.g. drm_gem_dma_dumb_create_internal) perform pitch/size
alignment in u32 arithmetic that can overflow for extreme
values. Add hard limits: width and height < 8192, bpp <= 32.
No legitimate software rendering use case exceeds these.
2. drm_mode_align_dumb() uses roundup(pitch, hw_pitch_align)
without checking for overflow. If pitch is near U32_MAX,
roundup() wraps to a small value, making subsequent
check_mul_overflow() pass with a much smaller pitch than
intended. Add an overflow check after roundup.
3. drm_mode_align_dumb() uses ALIGN(size, hw_size_align) which
only works correctly for power-of-two alignment values.
Replace with roundup() which works for any alignment.

Commit 8871389da151 introduces common pcs dts properties which writes
rx=normal,tx=normal polarity to register SGMSYS_QPHY_WRAP_CTRL of switch.
This is initialized with tx-bit set and so change inverts polarity
compared to before.
It looks like mt7531 has tx polarity inverted in hardware and set tx-bit
by default to restore the normal polarity.
The MT7531 datasheet quite clearly states:
Register 000050EC QPHY_WRAP_CTRL -- QPHY wrapper control
Reset value: 0x00000501
BIT 1 RX_BIT_POLARITY -- RX bit polarity control
1'b0: normal
1'b1: inverted
BIT 0 TX_BIT_POLARITY -- TX bit polarity control (TX default inversed
in MT7531)
1'b0: normal
1'b1: inverted
Till this patch the register write was only called when mediatek,pnswap
property was set which cannot be done for switch because the fw-node param
was always NULL from switch driver in the mtk_pcs_lynxi_create call.
Do not configure switch side like it's done before.

When mana_per_port_queue_reset_work_handler() runs after a previous
detach succeeded but attach failed, the port is left in a detached
state with apc->tx_qp and apc->rxqs already freed. Calling
mana_detach() again unconditionally leads to NULL pointer dereferences
during queue teardown.
Add an early exit in mana_detach() when the port is already in
detached state (!netif_device_present) for non-close callers, making
it safe to call idempotently. This allows the queue reset handler and
other recovery paths to simply retry mana_attach() without redundant
teardown.

When queue allocation fails partway through, the error cleanup frees
and NULLs apc->tx_qp and apc->rxqs. Multiple teardown paths such as
mana_remove(), mana_change_mtu() recovery, and internal error handling
in mana_alloc_queues() can subsequently call into functions that
dereference these pointers without NULL checks:
- mana_chn_setxdp() dereferences apc->rxqs[0], causing a NULL pointer
dereference panic (CR2: 0000000000000000 at mana_chn_setxdp+0x26).
- mana_destroy_vport() iterates apc->rxqs without a NULL check.
- mana_fence_rqs() iterates apc->rxqs without a NULL check.
- mana_dealloc_queues() iterates apc->tx_qp without a NULL check.
Add NULL guards for apc->rxqs in mana_fence_rqs(),
mana_destroy_vport(), and before the mana_chn_setxdp() call. Add a
NULL guard for apc->tx_qp in mana_dealloc_queues() to skip TX queue
draining when TX queues were never allocated or already freed.

If HID_DG_INPUTMODE is in a field other than the first one and the first
field has a report_count smaller than the usage_index of HID_DG_INPUTMODE,
this leads to an out-of-bounds write to r->field[0]->value.
Fix this by storing the field index of HID_DG_INPUTMODE in 'struct
hid_data' during feature mapping. In wacom_hid_set_device_mode(), use
this stored field index to access the correct field and add bounds
checks to ensure both the field index and the value index are within
valid ranges before writing.

Once FD_ADD() returns, the fd is live in the file descriptor table
and a thread sharing that table can close() it before DMA_BUF_TRACE()
runs. The close drops the last reference, __fput() frees the dma_buf,
and the tracepoint then dereferences dmabuf to take dmabuf->name_lock
-- slab-use-after-free.
Split FD_ADD() back into get_unused_fd_flags() + fd_install() and
emit the tracepoint between them. While the fdtable slot is reserved
with a NULL file pointer, a racing close() returns -EBADF without
entering __fput(), so the dma_buf stays alive across the trace. Same
approach as commit 2d76319c4cbb ("dma-buf: fix UAF in dma_buf_put()
tracepoint").
This undoes the FD_ADD() conversion done in commit 34dfce523c90
("dma: convert dma_buf_fd() to FD_ADD()"); FD_ADD() has no place to
hook the tracepoint safely.

Prevent _regmap_update_bits() from accessing hardware when the register
map is in cache-only mode.
Unlike regmap_raw_read() and _regmap_read(), the volatile
_regmap_update_bits() fast path bypasses the cache_only check. This can
result in unexpected hardware accesses while the device is suspended.
Return -EBUSY to ensure behavior is consistent with other cache-only
access paths.

Address several teardown issues and resource leaks in the driver's remove
path and error handling:
1. Debounce clock reference leak: The debounce clock (bank->db_clk) is
obtained using of_clk_get() which increments the clock's reference
count, but clk_put() is never called. Register a devm action to
cleanly release it on unbind. Note that of_clk_get(..., 1) remains
necessary over devm_clk_get() because the DT binding does not define
clock-names, precluding name-based lookup.
2. Unregistered chained IRQ handler: The chained IRQ handler is not
disconnected in remove(). If a stray interrupt fires after the driver
is removed, the kernel attempts to execute a stale handler, leading
to a panic. Fix this by clearing the handler in remove().
3. IRQ domain leak: The linear IRQ domain and its generic chips are
allocated manually during probe but never removed. Remove the IRQ
domain during driver teardown to free the associated generic chips
and mappings.

The bank->clk was previously obtained via of_clk_get() and manually
prepared/enabled. However, it was missing a corresponding clk_put() in
both the error paths and the remove function, leading to a reference leak.
Convert the allocation to devm_clk_get_enabled(), which also properly
propagates failures from clk_prepare_enable() that were previously ignored.
The GPIO bank device uses the same OF node as the previous of_clk_get()
call, so devm_clk_get_enabled(dev, NULL) correctly resolves the same
clock provider entry.
Fix the reference leak and simplify the code by removing the manual
clk_disable_unprepare() calls in the probe error paths and in the
remove function.
