ASoC: rt766: fix uninitialized stream_config->type
The stream_config variable was not initialized before being passed to
sdw_stream_add_slave().
This may cause unexpected behavior when configuring the SoundWire stream.

ALSA/ASoC: Intel: avs: HDAudio bus and general fixes
Cezary Rojewski <cezary.rojewski@intel.com> says:

The first half of the patchset concentrates on the driver initialization
procedure - a number of steps do not clean up after themselves when they
fail.  This is for both, HDAudio bus (ext) and the DSP part (avs) and
targets following procedures:

- stream initialization
- link initialization
- bus initialization

The next five are loosely related fixes.  First, split topology-loading
error handling from request-firmware one.  Currently -ENOENT coming from
topology-loading, which is a real error, is ignored.

Second, with deeper test coverage around corrupted firmware/DSP exception
handling, new issues are unearthed.  Switch to async d0ix_work
cancellation to avoid deadlock when D0IX has been scheduled just before
the recovery work.

The 09/10 patch, init_config change fixes possible out-of-bounds bug.
The fix is larger than what one could expect as instead of patching with
if-statements I've decided to refactor the parsing of init_configs.
The scenario that causes the problem no longer exists.
Note: the solution does not impose any changes on the existing topology
files (userspace).

The remaining two, IMHO are self-explanatory.

ASoC: Intel: avs: hda: Constrain MSBs on startup

ASoC: Intel: avs: Refactor and fix init_config access
Existing code accesses enties found in ->init_configs array through
indexes that are part of ->config_ids array.  Those two are limited by:
->num_init_configs and ->num_config_ids respectively.  Using ID larger
or equal to ->num_init_configs leads to out-of-bounds access:

avs_path_module_send_init_configs()
loop:
	(...) &acomp->tplg->init_configs[ids[i]]
					^ out-of-bounds candidate

Rather than adding another if-statement, refactor the code.  There is no
need to store the IDs, have a list of pointers to actual config-entries
instead.  As the verification of ->init_config entries does not differ from
verification of other types that are part of the topology.c file, simply
reuse the code.

avs_load_topology() combines request_firmware() and

ASoC: ux500: Fix MSP lifecycle, clocking and resources
Linus Walleij <linusw@kernel.org> says:

Repair independent correctness problems in the DB8500 multichannel
serial port driver. The series fixes duplex and repeated-prepare stream
ownership, error propagation, frame and divider programming, FIFO
watermarks, DAI validation, reset handling, and MMIO resource ownership.
It also removes obsolete PRCMU QoS calls which are unconditional stubs.

The register programming follows the DB8500 v2 reference manual. These
changes are independent of the later sound-card devicetree conversion.

which prepare then rejects.

before changing cached TDM state, and implement all four standard clock

ASoC: cs35l56: Fix probe deadlock waiting for SoundWire enumeration
On SoundWire, don't call snd_soc_register_component() from driver probe().
Instead, queue a work item after first SoundWire attach to call
snd_soc_register_component(). This prevents a deadlock if
snd_soc_register_component() directly calls cs35l56_component_probe().

On SoundWire, the registers are not accessible during driver probe().
Drivers must return from their probe() and wait for the SoundWire core
to call their update_status() callback to report an ATTACHED status. The
cs35l56 driver handled this by calling snd_soc_register_component() from
driver probe() as usual, and cs35l56_component_probe() waited for
init_completion to be signalled. A SoundWire attach calls cs35l56_init()
which then signals init_completion.

This created a deadlock if this was the last component needed to complete
a card. In that case, snd_soc_register_component() directly called
cs35l56_component_probe() which led to this:

    driver probe()
        calls snd_soc_register_component()
            calls cs35l56_component_probe()
                waits for init_completion

In this case the driver probe() has not returned, so the SoundWire core
would not call update_status() and init_completion would not be signalled.

Fortunately, snd_soc_register_component() never returns -EPROBE_DEFER, so
it doesn't need to be called from a driver probe(). It can be deferred to
a work item. This work is queued after the first completed pass through
cs35l56_init(), so there is no need for it to wait for init_completion.
snd_soc_register_component() isn't called directly from cs35l56_init()
because cs35l56_init() runs in the SoundWire bus driver thread, and there
would be a risk of nested locking or lock inversion.

The work item is queued on a freezable workqueue to prevent a race between
the work item and system_suspend of another instance. If the workqueue
were not frozen it would be possible for the work item of one driver
instance to call snd_soc_register_component() which then calls
cs35l56_component_probe() of another instance while that instance is
already executing its system suspend functions.

The non-SoundWire case still calls snd_soc_register_component() from
cs35l56_common_probe() so that it is the last initialization action.
There's no need defer the call for I2S/SPI buses so we can also leave it
able to return errors during probe.

ASoC: amd: renoir: fix disable_pdm_interrupts() to clear mask bits
disable_pdm_interrupts() uses |= ~PDM_DMA_INTR_MASK which sets all
bits except the PDM DMA interrupt bit instead of clearing only the
PDM DMA interrupt bit. Use &= ~PDM_DMA_INTR_MASK to clear only the
target bit.

ASoC: fsl_micfil: balance mclk enable/disable
hw_params() enables mclk unconditionally and hw_free() disables it
unconditionally, but the PCM core does not guarantee 1:1 pairing:
hw_free() can run without hw_params(), and hw_params() can be called
multiple times from the SETUP state. This triggers an "already
disabled" WARN() in the first case and leaks an enable reference in
the second, leaving the clock ungateable.

Guard both sides with the existing mclk_flag, as fsl_sai.c does with
mclk_streams.

ASoC: sprd: validate compress buffer sizes against fixed allocations
sprd_platform_compr_open() allocates the stage 0 IRAM buffer (32K data
area) and the stage 1 DDR buffer (2M data area) with fixed sizes, but
sprd_platform_compr_copy() derives all copy lengths from the user
controlled runtime->fragment_size and the write() count, never
comparing them against the physical buffer sizes. The compress core
only checks fragment_size * fragments for an u32 overflow in
snd_compress_check_input(), so a local user can configure a logical
buffer of up to ~4GB via SNDRV_COMPRESS_SET_PARAMS, far exceeding the
fixed allocations.

A fragment_size larger than the 32K IRAM data area makes the stage 0
copy_from_user() overflow past the IRAM allocation, and a buffer_size
larger than the 2M DDR buffer makes the wrapping copy at the end of
sprd_platform_compr_copy() write fully user controlled data past the
buffer. No SNDRV_PCM_TRIGGER_START is needed, a write() in SETUP
state reaches the copy callback directly.

Reject parameters that do not fit into the fixed buffers in
set_params(), and fix the advertised max fragment size: 128K never
fitted into the 32K IRAM buffer. The caps values may have been carried over
from the qdsp6 driver, which allocates its buffers according to the
advertised maxima, unlike this driver. With 32K as max fragment size
the advertised limits are self-consistent: 32K * 64 = 2M equals the
DDR buffer size.

ASoC: cs35l56: Fix pm_runtime imbalance if suspending before first attach
Remove the check for init_done in cs35l56_sdw_system_suspend(). Instead,
protect the call to cs35l56_mask_soundwire_interrupts() to only be done
if the amp is currently enumerated.

This fixes a runtime imbalance if cs35l56_sdw_system_suspend() is called
before the first SoundWire attach. This would skip the call to
pm_runtime_force_suspend() in cs35l56_system_suspend(). But resume
unconditionally called pm_runtime_force_resume() leading to an imbalance.

cs35l56_system_suspend() doesn't have any dependency on completion of
cs35l56_init(), so there is no need for the skip on !init_done in
cs35l56_sdw_system_suspend().

ASoC: tas2783-sdw: split a stereo stream across the two mono amps
A board with two TAS2783 aggregated on one link renders mono: the two
amplifiers are mono parts that each carry one channel of the stereo
stream, but snd_sdw_params_to_config() hands every codec the full
channel mask for playback.  The pair stays in mirror mode, both amps
render the same channel, and the other channel is never reproduced.

Claim a single channel per amplifier instead.  The index comes from the
machine-assigned component name prefix rather than the SoundWire
unique_id, which is board-specific: soc_sdw_ti_amp.c names the
amplifiers tas2783-1..4.

The bit that is set does not choose the side.  sdw_compute_slave_ports()
advances the payload offset by hweight32(ch_mask) and never looks at
which bit it is, so a one-channel mask fixes mono by defeating mirror
mode, and left and right then follow the amplifier's position in the
codec order of the DAI link.  That was measured: inverting the two masks
between the amplifiers does not move the audio.  On the boards this has
been run on the codec order matches the prefix numbering, so the sides
come out as the machine driver names them, but the mapping is not an ABI
promise the bus allocator could honour.

Pull locking fix from Ingo Molnar:

 - Revert a commit to spinlock cleanup guards that got caught up
   in the subtle limitations & fragility of guards (again...) and
   caused a regression (Peter Zijlstra)

f59c074e76 Rust fixes for v7.3
Toolchain and infrastructure:
 
  - Fix KCFI failures, such as in Rust doctests, by disabling function
    merging when CFI is enabled. Gary reported the LLVM bug to upstream
    and it is now fixed in their mainline.
 
  - Fix 'objtool' fallthrough warnings under the experimental
    'CONFIG_RUST_INLINE_HELPERS' by passing (for the combined Rust and
    helpers code) the LLVM options needed to preserve the unreachable
    traps that 'rustc' normally emits.
 
    In addition, fix 'objtool' errors when LTO is enabled on top, by
    also filtering out the LTO flags (for the combined Rust and helpers
    code) so that the traps are kept in place.
 
  - Fix 'objtool' warnings by adding one more 'noreturn' function.
 
  - Fix 'make rusttest' target when the 'rustc-dev' component is
    installed and Rust >= 1.82.0, <= 1.87.0 is used.
 
 'kernel' crate:
 
  - 'num' module: fix soundness issue in the 'Bounded' conversion from
    'bool' by restricting the conversions to unsigned 'Bounded'.
 
  - 'jump_label' module: fix future 'make rusttest' target failures when
    'ARCH=' is set to an arch different than the host's.
 
  - 'list' module: fix incorrect 'pop_back()' comment.

0fe792fa9b ARM updates for 7.3-rc1
- add module description for kprobes testing module
 - remove references to CONFIG_CPU_ARM92x_CPU_IDLE options
 - expand comment in ARM's __switch_to()
 
 Also a number of fixes that missed 7.2:
 
 - disable broken eBPF on RiscPC
 - more BKPT fixes (guys, it's a *very* bad idea when everyone uses
   the BKPT instruction for their own differing purposes.)
 - another preempt-rt fix, this time for siglock / CPU timers
 - fix another path where we try to send signals to processes
   with interrupts disabled
 - acquire mmap write lock for show_pte() with user faults
