751365035b ASoC: intel: sof_sdw: add .exit callback function 
We may allocate some resources in sof_sdw_codec_info .init function.
Adding a corresponding .exit function can help to release these resources.

5610921a44 ASoC: Intel: skl_hda_dsp_generic: Fix NULLptr dereference in autosuspend delay 
Different modules for HDMI codec are used depending on the
"hda_codec_use_common_hdmi" option being enabled or not. Driver private
context for both of them is different.
This leads to null-pointer dereference error when driver tries to set
autosuspend delay for HDMI codec while the option is off (hdac_hdmi
module is used for HDMI).

Change the string in conditional statement to "ehdaudio0D0" to ensure
that only the HDAudio codec is handled by this function.

5ca8f9a539 Merge series "ASoC: Intel: fix cppcheck warnings" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: 
This patchset tries to reduce the number of warnings on those drivers,
so that cppcheck can become a viable tool to detect issues (currently
hundreds of reports).

Most of the problems are related to unnecessary/redundant variable
assignments, prototypes and one nice logical mistake resulting in an
always-true condition.

a383308e50 ASoC: Intel: drop unnecessary list_empty 
list_for_each_entry_safe is able to handle an empty list.
The only effect of avoiding the loop is not initializing the
index variable.
Drop list_empty tests in cases where these variables are not
used.

Note that list_for_each_entry_safe is defined in terms of
list_first_entry, which indicates that it should not be used on an
empty list.  But in list_for_each_entry_safe, the element obtained by
list_first_entry is not really accessed, only the address of its
list_head field is compared to the address of the list head, so the
list_first_entry is safe.

The semantic patch that makes this change is as follows (with another
variant for the no brace case): (http://coccinelle.lip6.fr/)

<smpl>
@@
expression x,e;
iterator name list_for_each_entry_safe;
statement S;
identifier i,j;

5c5f1baee8 ASoC: Intel: kbl_rt5663_rt5514_max98927: Fix kabylake_ssp_fixup function 
kabylake_ssp_fixup function uses snd_soc_dpcm to identify the
codecs DAIs. The HW parameters are changed based on the codec DAI of the
stream. The earlier approach to get snd_soc_dpcm was using container_of()
macro on snd_pcm_hw_params.

The structures have been modified over time and snd_soc_dpcm does not have
snd_pcm_hw_params as a reference but as a copy. This causes the current
driver to crash when used.

This patch changes the way snd_soc_dpcm is extracted. snd_soc_pcm_runtime
holds 2 dpcm instances (one for playback and one for capture). 2 codecs
on the SSP are dmic (capture) and speakers (playback). Based on the
stream direction, snd_soc_dpcm is extracted from snd_soc_pcm_runtime.

Tested for all use cases of the driver.

ffc6d45d96 ASoC: intel/skl/hda - fix probe regression on systems without i915 
Starting in commit cbc7a6b5a8 ("ASoC: soc-card: add
snd_soc_card_add_dai_link()"), error value from ASoc add_dai_link() is
no longer ignored.

The generic HDA machine driver relied on the old semantics to disable
i915 HDMI/DP audio codec at runtime. If no display codec was present,
add_dai_link() returned an error, but this was ignored and rest of the
card was successfully probed.

Fix the problem by changing the machine driver add_dai_link() to not
return an error in this case.

The mc_private->hdmi_pcm_list is populated by elements loaded during

this is not true. Add a sanity check to sof_sdw_hdmi_card_late_probe()

cf0418cd06 ASoC: Intel: sof_sdw_rt711: remove properties in card remove 
The rt711 jack detection properties are set from the machine drivers
during the card probe, as done in other ASoC examples.

KASAN reports a use-after-free error when unbinding drivers due to a
confusing sequence between the ACPI core, the device core and the
SoundWire device cleanups.

Rather than fixing this sequence, follow the recommendation to have
the same caller add and remove properties, add an explicit
device_remove_properties() in the card .remove() callback.

In future patches the use of device_add/remove_properties will be
replaced by a direct handling of a swnode, but the sequence will
remain the same.
