Pull i2c fixes from Wolfram Sang:
"The biggest news here is that this is my last pull request as I2C
maintainer after 13.5 years. Starting with the 7.2 cycle, Andi Shyti
is taking over who helped me greatly maintaining the host drivers for
a while now. Thank you, Andi, and good luck with the subsystem. I'll
be around for help, of course.
Technically, there are two patches which might be a tad large for this
late cycle, but most of them is explaining comments, so I think they
are suitable.
- MAINTAINERS:
- hand over I2C maintainership to Andi
- minor updates
- rust: fix I2cAdapter refcount double increment
- imx: keep clock and pinctrl states consistent in runtime PM
- imx-lpi2c: fix DMA resource leaks on PIO fallback
- qcom-cci: fix NULL pointer dereference on remove

A job that GuC never scheduled (never started) indicates a GuC
scheduling failure; previously such jobs were silently errored out
instead of triggering a GT reset to recover. Trigger a GT reset and
resubmit them, but only when the queue was not already killed or banned:
an unstarted job on an already banned queue is the ban working as
intended and must neither clear the ban nor kick off a reset, otherwise
a banned userspace queue could be resurrected and spam GT resets.
Kernel queues are always recovered this way and wedge the device once
recovery attempts are exhausted, since kernel work must not silently
fail. A started job that times out on a userspace VM bind queue stays
banned rather than being reset and retried.
The queue is banned early in the timeout handler to signal the G2H
scheduling-done handler so it wakes the disable-scheduling waiter;
without it the waiter sleeps the full 5s timeout. When a reset is
warranted the ban is cleared before rearming so that
guc_exec_queue_start() can resubmit jobs after the GT reset - a
still-banned queue would block resubmission and cause an infinite TDR
loop. The already-banned case is gated out before this point via
skip_timeout_check, so it is unaffected.
v2: (Himal) Do it for any queue type, not just kernel/migration
v3: - (Sashiko and Sanjay): don't clear the ban / GT reset for already
killed/banned queues on unstarted-job timeout
- Update commit message
- (Matt) Add Fixes tag

xe_range_fence_insert() acquires a reference on fence via
dma_fence_get() and stores it in rfence->fence. It then calls
dma_fence_add_callback() and handles two cases: when the callback
is successfully registered (err == 0) the fence is transferred to
the tree for later cleanup; when the fence is already signaled
(err == -ENOENT) it manually drops the extra reference with
dma_fence_put(fence).
However, dma_fence_add_callback() can fail with other errors
(e.g. -EINVAL) and in that case the code falls through to the free:
label without releasing the acquired reference, leaking it.
Fix the leak by adding an else branch that calls dma_fence_put()
before jumping to free: for any error other than -ENOENT.

npc_cn20k_apply_custom_kpu() overwrites KPU profile entries with custom
firmware values and then calls npc_cn20k_update_action_entries_n_flags()
over all entries. Since the same function already ran during default
profile initialisation, entries not overridden by the custom firmware
get their flags translated twice, corrupting the CN20K-specific values.
Fix this by extracting the per-entry translation into a helper
npc_cn20k_translate_action_flags() and calling it as each custom entry
is loaded, removing the redundant batch call at the end.

When an XDP program uses bpf_xdp_adjust_head() or bpf_xdp_adjust_tail()
and then returns XDP_PASS, mvpp2 still builds the skb from fixed offsets
derived from the original RX descriptor. Packet geometry changes made by
the XDP program are therefore discarded before the skb reaches the stack.
Update rx_offset and rx_bytes from xdp.data and xdp.data_end for
XDP_PASS. This makes skb_reserve() and skb_put() reflect the packet seen
by XDP, and makes RX byte accounting for XDP_PASS follow the length of the
skb passed to the network stack.
Keep a separate rx_sync_size for page-pool recycling on skb allocation
failure, which must stay tied to the received buffer range.
Non-PASS verdicts continue to account the descriptor length because no skb
is passed up in those cases.

The RX error path returns the current descriptor buffer to the hardware
BM pool. That is only valid while the driver still owns the buffer.
mvpp2_rx_refill() can fail after the current buffer has been handed to
XDP or attached to an skb. In those cases mvpp2_run_xdp() may have
recycled, redirected, or queued the page for XDP_TX, and an skb free also
retires the data buffer. Returning such a buffer to BM lets hardware DMA
into memory that is no longer owned by the RX ring.
Refill the BM pool before handing the current buffer to XDP or to the

still-owned current buffer to BM, preserving the pool depth. Once the
refill succeeds, later local drops retire/free the current buffer instead
of returning it to BM.

mvpp2 has short and long BM pools, and short pool buffers can be smaller
than PAGE_SIZE. The XDP path nevertheless initializes every xdp_buff with
PAGE_SIZE as frame size.
XDP helpers use frame_sz to validate tail growth and to derive the hard
end of the data area. Advertising PAGE_SIZE for short buffers can let
bpf_xdp_adjust_tail() grow a packet past the real allocation, corrupting
memory or later tripping skb tailroom checks.
Initialize the XDP buffer with bm_pool->frag_size so XDP tailroom matches
the actual buffer backing the packet.

mvpp2 programs the RX queue packet offset, so hardware writes received
data at dma_addr + MVPP2_SKB_HEADROOM. The current CPU sync starts at
dma_addr and only covers rx_bytes + MVPP2_MH_SIZE bytes, which syncs the
unused headroom and misses the same number of bytes at the packet tail.
On non-coherent DMA systems this can leave the CPU reading stale cache
contents for the end of the received frame.
Use dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range
offset so the sync covers the Marvell header and packet data actually
written by hardware.

Context-based TLB invalidation currently selects only scheduling-active
exec queues via q->ops->active(). During rebind flows, queues may be
suspended (or transitioning through resume) while still owning valid
translations, causing them to be skipped from invalidation and leading
to missed TLB invalidations on LR rebinds.
The underlying issue is a TOCTOU: q->guc->state bits are flipped lock-free
from enable_scheduling(), disable_scheduling{,_deregister}(), the
suspend/resume sched-msg handlers, handle_sched_done(), and
guc_exec_queue_stop(); nothing in send_tlb_inval_ctx_ppgtt() serializes
against them, so any state-based predicate can race.
Include all the registered queues so that TLB invalidations are not
missed. This is race-free because list membership on vm->exec_queues.list
is stable under vm->exec_queues.lock held by the caller. The performance
impact is expected to be minimal and harmless. If it does turn out to be
a concern, we can come back with a race-safe solution to ignore certain
queues.

The xe driver keeps track of whether to probe display, and whether
display hardware is there, using xe->info.probe_display. It gets set to
false if there's no display after intel_display_device_probe(). However,
the display may also be disabled via fuses, detected at a later time in
intel_display_device_info_runtime_init().
In this case, the xe driver does for_each_intel_crtc() on uninitialized
mode config in xe_display_flush_cleanup_work(), leading to a NULL
pointer dereference, and generally calls display code with display info
cleared.
Check for intel_display_device_present() after
intel_display_device_info_runtime_init(), and reset
xe->info.probe_display as necessary. Also do unset_display_features()
for completeness, although display runtime init has already done
that. This will need to be unified across all cases later.
Move intel_display_device_info_runtime_init() call slightly earlier,
similar to i915, to avoid a bunch of unnecessary setup for no display
cases.
Note #1: The xe driver has no business doing low level display plumbing
like for_each_intel_crtc() to begin with. It all needs to happen in
display code.
Note #2: The actual bug is present already in commit 44e694958b95
("drm/xe/display: Implement display support"), but the oops was likely
introduced later at commit ddf6492e0e50 ("drm/xe/display: Make display

Commit d1d564ec49929 ("gpio: move hogs into GPIO core") introduced a
behaviour change that breaks boot on Raspberry Pi 5 when using the
firmware-supplied device tree:
gpiochip_add_data_with_key: GPIOs 544..575
(/soc@107c000000/gpio@7d517c00) failed to register, -22
brcmstb-gpio 107d517c00.gpio: Could not add gpiochip for bank 1
brcmstb-gpio 107d517c00.gpio: probe with driver brcmstb-gpio failed
with error -22
gpio-brcmstb registers two gpio_chips against the device tree
node gpio@7d517c00, one for each bank. The firmware-supplied DT includes
a gpio-hog on RP1 RUN, and this gpio-hog is attempted to be applied to
*both* gpio_chips. This succeeds against bank 0 (which hosts the GPIO)
and fails for bank 1 (which does not).
In the previous implementation, failures to apply gpio-hogs were
quietly ignored. In the new code, the error code propagates and causes
probe to fail.
Closely approximate the previous behaviour by using the OF_POPULATED flag
to ensure that each gpio-hog is processed only once. The flag was
previously being set before the gpio-hogs were processed, so as part
of this change, the flag now gets set only after the gpio-hog is actioned.
The handling of gpio-hogs on a DT node with multiple gpio_chips remains a
bit incomplete/unclear, but this at least retains the ability to apply
hogs to the first gpio_chip per node.

If gpiochip_hog_lines() successfully processes some hogs but fails on
a later one, the error handling path in gpiochip_add_data_with_key()

Use the right label in error path.

Commit a60fc3294a37 ("ptp: rework ptp_clock_unregister() to disable

configuration of pins if they support EXTTS events. In ptp_ocp_detach()
pins resources are freed before ptp_clock_unregister() and it leads to
use-after-free during driver removal. Fix it by changing the order of
free/unregister calls. To avoid irq handler running on the other core
while ptp device unregistering, call synchronize_irq() after HW is
configured to stop producing irqs and no irqs are in-flight.

tun_put_user() declares an on-stack struct virtio_net_hdr_v1_hash_tunnel
without zeroing it. For a non-tunnel skb, virtio_net_hdr_tnl_from_skb()
only initializes the first 10 bytes (sizeof(struct virtio_net_hdr)),
leaving bytes 10..23 (num_buffers and the hash/tunnel fields) as stack
garbage.
An unprivileged user can set the vnet header size to 24 with
TUNSETVNETHDRSZ, so __tun_vnet_hdr_put() copies all 24 bytes of the
partially-initialized struct to userspace, leaking 14 bytes of kernel
stack on every read of a non-tunnel packet.
Fix it the same way tun_get_user() already does by zeroing the whole
header right after declaration.

On SMP systems, dw_spi_handle_err() can be called from the SPI core
kthread while the IRQ handler is still accessing the FIFO on another
CPU. Resetting the chip via dw_spi_reset_chip() during an active FIFO
read/write causes a bus error.
Fix this by calling disable_irq() before the chip reset, which masks
the IRQ and waits for any in-flight handler to complete via
synchronize_irq(). This ensures no handler is accessing the FIFO when
the reset occurs.

TPM TIS SPI probe fails with:
tpm_tis_spi: probe of spi11.0 failed with error -110
TPM TIS SPI sets cs_change=1 on single-transfer messages to keep CS
asserted across the header, wait-state, and data phases of a transaction.
CS deassertion between these phases violates the TCG SPI flow control
specification.
This bug was introduced by commit b99181cdf9fa ("spi-geni-qcom: remove
manual CS control"), which replaced manual CS control with automatic CS
control via the FRAGMENTATION bit. The FRAGMENTATION bit controls CS
behavior after a transfer: when set to 1, CS remains asserted; when
cleared to 0, CS is deasserted.
The commit correctly sets FRAGMENTATION for non-last transfers with
cs_change=0 to keep CS asserted between chained transfers, but misses the
case where cs_change=1 is set on the last transfer. When cs_change=1 on
the last transfer, the client requests CS to remain asserted after the
message completes, so FRAGMENTATION must be set to 1 in this case as well.
Fix setup_se_xfer() to set FRAGMENTATION when cs_change=1 on the last
transfer.
Also fix the same missing case in setup_gsi_xfer() and correct it to
write 1 instead of the raw bitmask FRAGMENTATION (value 4) to
peripheral.fragmentation. This field is a 1-bit boolean consumed by
gpi_create_spi_tre() via u32_encode_bits(..., TRE_SPI_GO_FRAG). Writing 4
to a 1-bit field causes u32_encode_bits() to mask it to 0, silently
disabling the FRAGMENTATION bit in the GPI TRE regardless of the
cs_change logic.

iommu_dma_iova_link_swiotlb() processes a mapping that is unaligned in three
parts, the head, middle and trailer. If the middle is empty because there
are no aligned pages it will call down to iommu_map() with a 0 size
which the iommupt implementation will fail as illegal.
It then tries to do an error unwind and starts from the wrong spot
corrupting the mapping so the eventual destruction triggers a WARN_ON.
Check for 0 length and avoid mapping and use offset not 0 as the starting
point to unlink.
This is frequently triggered by using some kinds of thunderbolt NVMe
drives that trigger forced SWIOTLB for unaligned memory. NVMe seems to
pass in oddly aligned buffers for the passthrough commands from smartctl
that hit this condition.

Don't just overwrite the original pointer passed to krealloc()
with its return value without checking latter:
MEM = krealloc(MEM, SZ, GFP);
If krealloc() returns NULL, that erases the pointer
to the still allocated memory, hence leaks this memory.
Instead, use a temporary variable, check it's not NULL
and only then assign it to the original pointer:
TMP = krealloc(MEM, SZ, GFP);
if (!TMP) return;
MEM = TMP;
While on it, use krealloc_array().
