[ Upstream commit c4e51e424e ]
For shutting up spurious KMSAN uninit-value warnings, just replace
kmalloc() calls with kzalloc() for the buffers used for
communications. There should be no real issue with the original code,
but it's still better to cover.

commit 1576f263ee upstream.
This patch addresses an issue with the Panasonic CF-SZ6's existing quirk,
specifically its headset microphone functionality. Previously, the quirk
used ALC269_FIXUP_HEADSET_MODE, which does not support the CF-SZ6's design
of a single 3.5mm jack for both mic and audio output effectively. The
device uses pin 0x19 for the headset mic without jack detection.
Following verification on the CF-SZ6 and discussions with the original
patch author, i determined that the update to
ALC269_FIXUP_ASPIRE_HEADSET_MIC is the appropriate solution. This change
is custom-designed for the CF-SZ6's unique hardware setup, which includes
a single 3.5mm jack for both mic and audio output, connecting the headset
microphone to pin 0x19 without the use of jack detection.

[ Upstream commit fc563aa900 ]
In snd_soc_info_volsw(), mask is generated by figuring out the index of
the most significant bit set in max and converting the index to a
bitmask through bit shift 1. Unintended wraparound occurs when max is an
integer value with msb bit set. Since the bit shift value 1 is treated
as an integer type, the left shift operation will wraparound and set
mask to 0 instead of all 1's. In order to fix this, we type cast 1 as
`1ULL` to prevent the wraparound.

commit 051e0840ff upstream.
The dreamcastcard->timer could schedule the spu_dma_work and the
spu_dma_work could also arm the dreamcastcard->timer.
When the snd_pcm_substream is closing, the aica_channel will be
deallocated. But it could still be dereferenced in the worker
thread. The reason is that del_timer() will return directly
regardless of whether the timer handler is running or not and
the worker could be rescheduled in the timer handler. As a result,
the UAF bug will happen. The racy situation is shown below:
(Thread 1) | (Thread 2)
snd_aicapcm_pcm_close() |
... | run_spu_dma() //worker
| mod_timer()
flush_work() |
del_timer() | aica_period_elapsed() //timer
kfree(dreamcastcard->channel) | schedule_work()
| run_spu_dma() //worker
... | dreamcastcard->channel-> //USE
In order to mitigate this bug and other possible corner cases,
call mod_timer() conditionally in run_spu_dma(), then implement
PCM sync_stop op to cancel both the timer and worker. The sync_stop
op will be called from PCM core appropriately when needed.

By default, when mclk-fs is not provided, the tdm-interface driver
requests an MCLK that is 4x the bit clock, SCLK.
However there is no justification for this:
* If the codec needs MCLK for its operation, mclk-fs is expected to be set
according to the codec requirements.
* If the codec does not need MCLK the minimum is 2 * SCLK, because this is
minimum the divider between SCLK and MCLK can do.
Multiplying by 4 may cause problems because the PLL limit may be reached
sooner than it should, so use 2x instead.

commit c7a6065195 upstream.
As reported recently, ALSA core info helper may cause a deadlock at
the forced device disconnection during the procfs operation.
The proc_remove() (that is called from the snd_card_disconnect()
helper) has a synchronization of the pending procfs accesses via
wait_for_completion(). Meanwhile, ALSA procfs helper takes the global
mutex_lock(&info_mutex) at both the proc_open callback and
snd_card_info_disconnect() helper. Since the proc_open can't finish
due to the mutex lock, wait_for_completion() never returns, either,
hence it deadlocks.
TASK#1 TASK#2
proc_reg_open()
takes use_pde()
snd_info_text_entry_open()
snd_card_disconnect()
snd_info_card_disconnect()
takes mutex_lock(&info_mutex)
proc_remove()
wait_for_completion(unused_pde)
... waiting task#1 closes
mutex_lock(&info_mutex)
=> DEADLOCK
This patch is a workaround for avoiding the deadlock scenario above.
The basic strategy is to move proc_remove() call outside the mutex
lock. proc_remove() can work gracefully without extra locking, and it
can delete the tree recursively alone. So, we call proc_remove() at
snd_info_card_disconnection() at first, then delete the rest resources
recursively within the info_mutex lock.
After the change, the function snd_info_disconnect() doesn't do
disconnection by itself any longer, but it merely clears the procfs
pointer. So rename the function to snd_info_clear_entries() for
avoiding confusion.
The similar change is applied to snd_info_free_entry(), too. Since
the proc_remove() is called only conditionally with the non-NULL
entry->p, it's skipped after the snd_info_clear_entries() call.

[ Upstream commit 67de40c9df ]
Before committing 79597c8bf6, *rac97 always be NULL if there is
an error. When error happens, make sure *rac97 is NULL is safer.
For examble, in snd_vortex_mixer():
err = snd_ac97_mixer(pbus, &ac97, &vortex->codec);
vortex->isquad = ((vortex->codec == NULL) ?
0 : (vortex->codec->ext_id&0x80));
If error happened but vortex->codec isn't NULL, this may cause some
problems.
Move the judgement order to be clearer and better.

[ Upstream commit f85739c0b2 ]
The 8K sample parameter of 12.288Mhz main system bus clock doesn't work
because the I2SC_MR.IMCKDIV must not be 0 according to the sama5d2
series datasheet(I2SC Mode Register of Register Summary).
So use the 6.144Mhz instead of 12.288Mhz to support 8K sample.

[ Upstream commit f0691dc162 ]
When handling an AAD interrupt, if IRQ events read failed (for example,
due to i2c "Transfer while suspended" failure, i.e. when attempting to
read it while DA7219 is suspended, which may happen due to a spurious
AAD interrupt), the events array contains garbage uninitialized values.
So instead of trying to interprete those values and doing any actions
based on them (potentially resulting in misbehavior, e.g. reporting
bogus events), refuse to handle the interrupt.

[ Upstream commit 91e292917d ]
da7219_aad_suspend() disables jack detection, which should prevent
generating new interrupts by DA7219 while suspended. However, there is a
theoretical possibility that there is a pending interrupt generated just
before suspending DA7219 and not handled yet, so the IRQ handler may
still run after DA7219 is suspended. To prevent that, wait until the
pending IRQ handling is done.
This patch arose as an attempt to fix the following I2C failure
occurring sometimes during system suspend or resume:

which indicates that the AAD IRQ handler is unexpectedly running when
DA7219 is suspended, and as a result, is trying to read data from DA7219
over I2C and is hitting the I2C driver "Transfer while suspended"
failure.
However, with this patch the above failure is still reproducible. So
this patch does not fix any real observed issue so far, but at least is
useful for confirming that the above issue is not caused by a pending
IRQ but rather looks like a DA7219 hardware issue with an IRQ
unexpectedly generated after jack detection is already disabled.
