Commit e576e7843c ("ALSA: ctxfi: Simplify dao_clear_{left,right}_input() functions")
centralized the DAO input mapper clearing logic in
dao_clear_input(), but omitted the kfree() calls.
It removes the mapper entries from the list and sets their pointers
to NULL without freeing the allocated array. This leaks memory each
time dao_clear_input() is called.
Store the base pointer of the allocation before clearing the mapper
entries and free the array after removing entries from the list.

We used the auto-cleanup via snd_card_unref() for errors at probe of
ice1712 driver, but this may be problematic in a subtle way when an
error happens at snd_card_register(); since snd_card_unref() skips the
snd_card_disconnect() call, it may miss some resource clearance.
For fixing the issue, use the new __free(snd_card_free) instead, which
does call snd_card_free() explicitly at errors for avoiding such a
pitfall.

Commit 4b490e0d10 ("ALSA: ctxfi: Add ADC helper functions for GPIO")
moved the GPIO_DATA read into hw_adc_stop(), but the Titanium HD
(SB1270) setup in hw_adc_init() uses the local data variable holding
the GPIO_CTRL value.
Writing this value to GPIO_DATA sets the output mute bits. Playback
runs without errors, but the outputs stay muted.
Re-read GPIO_DATA before setting the speed mode bits. Also, add the
delay after writing the mode bits, as in the original sequence.
On affected kernels, switching the output selection was reported to
restore clean playback.

The RME HDSPe AIO PCI express audio card has a new PCI vendor ID (1d18)
while keeping the same device ID (3fc6). The card seems working fine by
just adding the new ID.
While we're at it, use the standard macro to cleann up the existing PCI
ID entry, too.

dao_rsc_init() encodes the DAIO configuration as
conf = (desc->msr & 0x7) | (desc->passthru << 3);
S/PDIF passthrough uses msr=1 and passthru=1, resulting in
conf=9.
daio_mgr_dao_init() masks conf with 0xf, but handles only values
1, 2, 4 and 8 when programming ATXCTL_NUC. As a result, conf=9
falls through to the default case and leaves NUC at its previous
setting.
On a Creative X-Fi Titanium HD SB1270 (CA20K2), this breaks AC3
IEC61937 passthrough when snd_ctxfi runs with
reference_rate=48000,multiple=2. The receiver detects a non-audio
stream but cannot decode the AC3 payload.
With the unmodified driver, multiple=1 makes the same stream work.
Handle conf=9 through the same NUC=0 path as conf=1.
The change was runtime tested on the SB1270 with multiple=2 using
IEC958 stereo PCM, pre-encoded AC3 IEC61937 passthrough and ALSA
A52 live 5.1 encoding.

This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci
This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.
Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.

Replace manual ioremap() calls with pcim_iomap() which uses devres
for automatic cleanup. This eliminates the need for manual iounmap()
in both the error path of asihpi_adapter_probe() and the
asihpi_adapter_remove() function.
The pcim_iomap() helper is cleaner and less error-prone since it
handles unmapping automatically when the PCI device is released.

The lx6464es driver advertises both 16-bit and packed 24-bit PCM formats,
but lx_trigger_start() and lx_interrupt_request_new_buffer() calculate the
DMA period size as runtime->period_size * runtime->channels * 3. That is
only correct for the packed 24-bit formats.
For 16-bit streams the driver submits buffers that are 50% larger than the
actual ALSA period and advances the DMA address by the same wrong amount.
For example, with 2 channels, 256 frames and 4 periods, the third buffer
already extends beyond the ALSA buffer and the fourth buffer starts outside
it.
Use snd_pcm_lib_period_bytes() so the byte count matches the runtime
format, channel count and period size.

This folds the BAR1 reserve and iomap into one managed call. The

Move the complete encoding into pcxhr_pll_freq_register() and pass each

The independent surround playback open path rejects a substream when the
matching PDMA channel is reserved by the multi-channel PDMA0 stream. It
currently returns -EBUSY for that case, although the driver has carried a
FIXME noting that blocking mode is not handled properly.
ALSA PCM open waits and retries only when the low-level open callback
returns -EAGAIN. Returning -EBUSY therefore makes blocking opens fail
immediately, the same as nonblocking opens.
Return -EAGAIN for the temporary PDMA0 reservation conflict. The PCM core
continues to report -EBUSY for O_NONBLOCK callers, while blocking callers
sleep and retry.
Also wake the independent surround PCM wait queue when hw_free releases a
PDMA reservation. The reservation can be released by the pro PCM, while
waiters are sleeping on the independent surround PCM, so waking the current
substream PCM is not sufficient for this cross-PCM reservation.

ctxfi stores the Line Capture Switch and Mic Capture Switch controls in
a file-scope kctls[] array so do_line_mic_switch() can notify the
opposite control when the shared line/mic input selection changes.
That storage is shared by all ctxfi cards. If more than one X-Fi card is
present, a later card can overwrite the pointers saved by an earlier one.
A control update on one card can then use another card's kcontrol object
for snd_ctl_notify(). If that other card is removed, the saved pointer can
also become stale.
Store those notification targets in struct ct_mixer instead. The mixer is
per-card state and matches the lifetime of the controls created for that
card.

... and PCI device helpers.
The various struct pci_device_id arrays were initialized mostly by list
expressions, some of them using the PCI_DEVICE macros. This isn't easily
readable if you're not into PCI. Using named initializers is more
explicit and thus easier to parse. Also use PCI_DEVICE* helper macros to
assign .vendor, .device, .subvendor and .subdevice where appropriate and
skip explicit assignments of 0 (which the compiler takes care of).
The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.

snd_als4000_capture_trigger() updates chip->mode under mixer_lock,
while snd_als4000_set_rate() and snd_als4000_playback_trigger()
serialize the same rate-lock state with reg_lock.
The PCM core serializes callbacks only per acted-on substream, or for an
explicitly linked group, so unlinked playback and capture streams can
run concurrently.
That leaves two races on ALS4000 rate-lock state:
- playback and capture trigger callbacks can concurrently update
chip->mode and lose one of the SB_RATE_LOCK bits
- snd_als4000_set_rate() can observe chip->mode without the capture
lock bit set and reprogram the shared sample rate while capture is
being started
Fix this by taking reg_lock as the outer lock in
snd_als4000_capture_trigger() and nesting mixer_lock only for the CR1E
write. This keeps chip->mode serialized with the rest of the ALS4000
rate-lock users while preserving the existing CR1E programming
sequence.

spdif_passthru_playback_get_resources() uses atc->pll_rate as the RSR
for the MSR calculation loop. However, pll_rate is only updated in
atc_pll_init() and not in hw_pll_init(), so it remains 0 after the
card init.
When spdif_passthru_playback_setup() skips atc_pll_init() for
32000 Hz, (rsr * desc.msr) always becomes 0, causing the loop to spin
indefinitely.
Add fallback to use atc->rsr when atc->pll_rate is 0. This reflects
the hardware state, since hw_card_init() already configures the PLL
to the default RSR.

The recent refactoring of xfi driver changed the assignment of
atc->daios[] at atc_get_resources(); now it loops over all enum
DAIOTYP entries while it looped formerly only a part of them.
The problem is that the last entry, SPDIF1, is a special type that
is used only for hw20k1 CTSB073X model (as a replacement of SPDIFIO),
and there is no corresponding definition for hw20k2. Due to the lack
of the info, it caused a kernel crash on hw20k2, which was already
worked around by the commit b045ab3dff ("ALSA: ctxfi: Fix missing
SPDIFI1 index handling").
This patch addresses the root cause of the regression above properly,
simply by skipping the incorrect SPDIF1 type in the parser loop.
For making the change clearer, the code is slightly arranged, too.
