The sanity check previously added to uaudio_transfer_buffer_setup()
assumed the allocated buffer being linear-mapped. But the buffer
allocated via usb_alloc_coherent() isn't always so, rather to be used
with (SG-)DMA API. This leaded to a false-positive warning and the
driver failed to work.
Actually uaudio_transfer_buffer_setup() deals only with the DMA-API
addresses for MEM_XFER_BUF type, while other callers of
uaudio_iommu_map() are with pages with physical addresses for
MEM_EVENT_RING and MEM_XFER_RING types. So this patch splits the
mapping helper function to two different ones, uaudio_iommu_map() for
the DMA pages and uaudio_iommu_map_pa() for the latter, in order to
handle mapping differently for each type. Along with it, the
unnecessary address check that caused probe error is dropped, too.

The ALSA HwDep character device of the firewire-motu driver incorrectly
returns EPOLLOUT in poll(2), even though the driver implements no operation
for write(2). This misleads userspace applications to believe write() is
allowed, potentially resulting in unnecessarily wakeups.
This issue dates back to the driver's initial code added by a commit
71c3797779 ("ALSA: firewire-motu: add hwdep interface"), and persisted
when POLLOUT was updated to EPOLLOUT by a commit a9a08845e9 ('vfs: do

For Intel SKL and KBL platforms, it may be bound with one of three
HD-audio drivers (AVS, SOF and legacy). AVS is the preferred one when
DMIC is detected, and that's how it's defined in the snd-intel-dspcfg
config table.
But, when AVS driver is disabled (CONFIG_SND_SOC_INTEL_AVS=n), the
device may be bound freely with either SOF or legacy driver.
Before 6.17, the legacy driver took it primarily, but on 6.17, likely
due to the recent code shuffling, SOF driver seems taking it at first,
and fails to probe. For avoiding the regression, we should enforce to
bind those with the legacy HD-audio drvier when AVS is disabled.
This patch adds the extra two entries in intel-dspcfg table that are
applied only when CONFIG_SND_SOC_INTEL_AVS=n, for binding with the
legacy driver.
Note that there are entries for APL in that config table block, but
APL may be supported by SOF for certain setups, so the choice can't be
exclusive. Hence this patch includes only SKL and KBL.

Merge tag 'asoc-fix-v6.17-rc1' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v6.17
A reasonably small collection of fixes that came in since the merge
window, mostly small and driver specific plus a cleanup of the menu
reorganisation to address some user confusion with the way the generic
drivers had been handled.
On a motherboard with an AMD Granite Ridge CPU there is a report
that 3.5mm microphone and headphones aren't working. In the
log it's observed:
snd_hda_intel 0000:02:00.6: Skipping the device on the denylist
This was because of commit df42ee7e22 ("ALSA: hda: Add ASRock
X670E Taichi to denylist"). Reverting this commit allows the
microphone and headphones to work again. As at least some combinations
of this motherboard do have applicable devices, revert so that they
can be probed.

Some inline functions are unused depending on kconfig, and the recent
change for clang builds made those handled as errors with W=1.
For avoiding pitfalls, mark those with __maybe_unused attributes.

calc_clk_div() will only return a non-zero value (-EINVAL)
in case of error. On the other hand, req->rate is an unsigned long.
It seems quite odd that req->rate would be assigned a negative value,
which is clearly not a rate, and success would be returned.
Reinstate previous logic, which would just return error.

In aw8xxxx_profile_info(), strscpy() is called with the length of the
source string "null" rather than the size of the destination buffer.
This is fine as long as the destination buffer is larger than the source
string, but we should still use the destination buffer size instead to
call strscpy() as intended. And since 'name' points to the fixed-size
buffer 'uinfo->value.enumerated.name', we can safely omit the size
argument and let strscpy() infer it using sizeof() and remove 'name'.
