The array wm_adsp_fw_find_test_dir_all_files[] needs a NULL terminator.
It was documented at line 41 that dir_files points to a NULL-terminated
array.
/* NULL-terminated array of pointers to filenames ... <snip> */
const char * const *dir_files;
This fixes the error reported by KASAN:

Jihed Chaibi <jihed.chaibi.dev@gmail.com> says:
adau1372_set_power() had two related error handling issues in its enable
path: clk_prepare_enable() was called but its return value discarded, and
adau1372_enable_pll() was a void function that silently swallowed lock
failures, leaving mclk enabled and adau1372->enabled set to true despite
the device being in a broken state.
Patch 1 fixes the unchecked clk_prepare_enable() by making
adau1372_set_power() return int and propagating the error.
Patch 2 converts adau1372_enable_pll() to return int and adds a full
unwind in adau1372_set_power() if PLL lock fails, reversing the regcache,
GPIO power-down, and clock state.
|
|
adau1372_enable_pll() was a void function that logged a dev_err() on
PLL lock timeout but did not propagate the error. As a result,
adau1372_set_power() would continue with adau1372->enabled set to true
despite the PLL being unlocked, and the mclk left enabled with no
corresponding disable on the error path.
Convert adau1372_enable_pll() to return int, using -ETIMEDOUT on lock
timeout and propagating regmap errors directly. In adau1372_set_power(),
check the return value and unwind in reverse order: restore regcache to
cache-only mode, reassert GPIO power-down, and disable the clock before
returning the error.

adau1372_set_power() calls clk_prepare_enable() but discards the return
value. If the clock enable fails, the driver proceeds to access registers
on unpowered hardware, potentially causing silent corruption.
Make adau1372_set_power() return int and propagate the error from
clk_prepare_enable(). Update adau1372_set_bias_level() to return the
error directly for the STANDBY and OFF cases.

Convert the Hisilicon DesignWare Mobile Storage Host Controller
(dw-mshc) bindings from text format to DT schema.
As part of this conversion, the binding file is renamed from
k3-dw-mshc.txt to hisilicon,hi3660-dw-mshc.yaml to align with compatible
string naming conventions. Examples have been updated to pass schema
validation.
Note: synopsys-dw-mshc binding specifies clock names as "biu" followed
by "ciu". However, this Hisilicon binding reverses the order to 'ciu'
then 'biu' to match both the legacy text binding and in-kernel Hisilicon
DTS board files.

A typical bridge refcount value is 3 after a bridge chain is formed:
- devm_drm_bridge_alloc() initializes the refcount value to be 1.
- drm_bridge_add() gets an additional reference hence 2.
- drm_bridge_attach() gets the third reference hence 3.
This typical refcount value aligns with allbridges_show()'s behaviour.
However, since encoder_bridges_show() uses
drm_for_each_bridge_in_chain_scoped() to automatically get/put the
bridge reference while iterating, a bogus reference is accidentally
got when showing the wrong typical refcount value as 4 to users via
debugfs. Fix this by caching the refcount value returned from
kref_read() while iterating and explicitly decreasing the cached
refcount value by 1 before showing it to users.

Due to errata i2493[0], multi-block write would still fail in retries.
With i2493, the MMC interface has the potential of write failures when
issuing multi-block writes operating in HS200 mode with excessive IO
supply noise.
While the errata provides guidance in hardware design and layout to
minimize the IO supply noise, in theory the write failure cannot be
resolved in hardware. The software solution to ensure the data integrity
is to add minimum 5us delay between block writes. Single-block write is
the practical way to introduce the delay.
This patch reuses recovery_mode flag, and switches to single-block
write in retry when multi-block write fails. It covers both CQE and
non-CQE cases.

If a software node defining an LED is missing explicit 'label', 'color',
or 'function' properties, led_compose_name() currently fails with
-EINVAL, because fallback to using node name in place of LED name/label
is only implemented for OF nodes.
Implement similar fallback for software nodes. Unlike OF nodes, which
use the short 'name' attribute of the device tree node to avoid
including the address block, use fwnode_get_name() directly since
swnodes do not include an address block and always have a valid name.

The AF_ALG interface fails to unmark the end of a Scatter/Gather List (SGL)
when chaining a new af_alg_tsgl structure. If a sendmsg() fills an SGL
exactly to MAX_SGL_ENTS, the last entry is marked as the end. A subsequent
sendmsg() allocates a new SGL and chains it, but fails to clear the end
marker on the previous SGL's last data entry.
This causes the crypto scatterwalk to hit a premature end, returning NULL
on sg_next() and leading to a kernel panic during dereference.
Fix this by explicitly unmarking the end of the previous SGL when
performing sg_chain() in af_alg_alloc_tsgl().

The code in deflate_decompress_one may erroneously return -ENOSPC even if
it didn't run out of output space. The error happens under this
condition:
- Suppose that there are two input pages, the compressed data fits into
the first page and the zlib checksum is placed in the second page.
- The code iterates over the first page, decompresses the data and fully
fills the destination buffer, zlib_inflate returns Z_OK becuse zlib
hasn't seen the checksum yet.
- The outer do-while loop is iterated again, acomp_walk_next_src sets the
input parameters to the second page containing the checksum.
- We go into the inner do-while loop, execute "dcur =
acomp_walk_next_dst(&walk);". "dcur" is zero, so we break out of the
loop and return -ENOSPC, despite the fact that the decompressed data
fit into the destination buffer.
In order to fix this bug, this commit changes the logic when to report
the -ENOSPC error. We report the error if the destination buffer is empty
*and* if zlib_inflate didn't make any progress consuming the input
buffer. If zlib_inflate consumes the trailing checksum, we see that it
made progress and we will not return -ENOSPC.

When a key longer than block size is supplied, it is copied and then
hashed into the real key. The memory allocated for the copy needs to
be rounded to DMA cache alignment, as otherwise the hashed key may
corrupt neighbouring memory.
The copying is performed using kmemdup, however this leads to an overflow:
reading more bytes (aligned_len - keylen) from the keylen source buffer.
Fix this by replacing kmemdup with kmalloc, followed by memcpy.

providing a legacy compatibility alias.

The async_hold queue pins encrypted input skbs while
the AEAD engine references their scatterlist data. Once
tls_decrypt_async_wait() returns, every AEAD operation
has completed and the engine no longer references those
skbs, so they can be freed unconditionally.
A subsequent patch adds batch async decryption to
tls_sw_read_sock(), introducing a new call site that
must drain pending AEAD operations and release held
skbs. Move __skb_queue_purge(&ctx->async_hold) into
tls_decrypt_async_wait() so the purge is centralized
and every caller -- recvmsg's drain path, the -EBUSY
fallback in tls_do_decryption(), and the new read_sock
batch path -- releases held skbs on synchronization
without each site managing the purge independently.
This fixes a leak when tls_strp_msg_hold() fails part-way through,
after having added some cloned skbs to the async_hold
queue. tls_decrypt_sg() will then call tls_decrypt_async_wait() to
process all pending decrypts, and drop back to synchronous mode, but
tls_sw_recvmsg() only flushes the async_hold queue when one record has
been processed in "fully-async" mode, which may not be the case here.

Suspend may fail on i.MX8QM when Falling Edge is used as a pad wakeup
trigger due to a hardware bug in the detection logic. Since the hardware
does not support Both Edge wakeup, remap requests for Both Edge to Rising
Edge by default to avoid hitting this issue.
A warning is emitted when Falling Edge is selected on i.MX8QM.

proc_do_large_bitmap() does not initialize variable c, which is expected
to be set to a trailing character by proc_get_long().
However, proc_get_long() only sets c when the input buffer contains a
trailing character after the parsed value.
If c is not initialized it may happen to contain a '-'. If this is the
case proc_do_large_bitmap() expects to be able to parse a second part of
the input buffer. If there is no second part an unjustified -EINVAL will
be returned.
Initialize c to 0 to prevent returning -EINVAL on valid input.

veml6070_read() computes the sensor value in ret but
returns 0 instead of the actual result. This causes
veml6070_read_raw() to always report 0.
Return the computed value instead of 0.
Running make W=1 returns no errors. I was unable
to test the patch because I do not have the hardware.
Found by code inspection.
