The various list iterators are able to handle an empty list.
The only effect of avoiding the loop is not initializing some

Drop list_empty tests in cases where these variables are not

PulseAudio (and perhaps other userspace utilities) can not detect any
jack for rk3399_gru_sound as the driver doesn't expose related Jack
kcontrols.
This patch adds two DAPM pins to the headset jack, where the
snd_soc_card_jack_new() call automatically creates "Headphones Jack" and
"Headset Mic Jack" kcontrols from them.
With an appropriate ALSA UCM config specifying JackControl fields for
the "Headphones" and "Headset" (mic) devices, PulseAudio can detect
plug/unplug events for both of them after this patch.

According to the WM8962 datasheet, there is no register at address 0x200.
WM8962_GPIO_BASE is just a base address for the GPIO registers and not a
real register, so remove it from wm8962_readable_register().
Also, Register 515 (WM8962_GPIO_BASE + 3) does not exist, so skip
its access.
This fixes the following errors:
wm8962 0-001a: ASoC: error at soc_component_read_no_lock on wm8962.0-001a: -16

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/)

After carefully checking, it appears that both tdmout and tdmin require the
rising edge of the sclk they get to be synchronized with the frame sync
event (which should be a rising edge of lrclk).
TDMIN was improperly set before this patch. Remove the sclk_invert quirk
which is no longer needed and fix the sclk phase.

This set of patches is required for facilitating system S0ix
entry when the DSP is in D0I3. This first patch adds the missing
CORB/RIRB DMA stop and restart to the suspend/resume sequence along
with powering up/down the links. The second patch ensures that the
FW traces are disabled when the system enters S0ix with the DSP in D0I3.

Right now the direction of a DAI has to be specified as a literal
number in the device tree, e.g.:
dai@0 {
reg = <0>;
direction = <2>;
};
but this does not make it immediately clear that this is a
playback/RX-only DAI.
Actually, q6asm-dai.c has useful defines for this. Move them to the
dt-bindings header to allow using them in the dts(i) files.
The example above then becomes:
dai@0 {
reg = <0>;
direction = <Q6ASM_DAI_RX>;
};
which is immediately recognizable as playback/RX-only DAI.

PME_EN state needs to restored to the value set by fmw.
For the devices which are not using I2S wake event which gets
enabled by PME_EN bit, keeping PME_EN enabled burns considerable amount
of power as it blocks low power state.
For the devices using I2S wake event, PME_EN gets enabled in fmw and the
state should be maintained after ACP Power On.

runtime_usage of sound card has been observed to grow without bound.
For example:
$ cat /sys/devices/platform/sound/power/runtime_usage
46
$ sox -n -t s16 -r 48000 -c 2 - synth 1 sine 440 vol 0.1 | \
aplay -q -D hw:0,0 -f S16_LE -r 48000 -c 2
$ cat /sys/devices/platform/sound/power/runtime_usage
52
Commit 4e872a4682 ("ASoC: dapm: Don't force card bias level to be
updated") stops to force update bias_level on card. If card doesn't
provide set_bias_level callback, the snd_soc_dapm_set_bias_level()
is equivalent to NOP for card device.
As a result, dapm_pre_sequence_async() doesn't change the bias_level of
card device correctly. Thus, pm_runtime_get_sync() would be called in
dapm_pre_sequence_async() without symmetric pm_runtime_put() in
dapm_post_sequence_async().
Don't call pm_runtime_* on card device.

At the moment we have two separate functions to parse the sound card
properties from the device tree: qcom_snd_parse_of() for DPCM and
apq8016_sbc_parse_of() without DPCM. These functions are almost identical
except for a few minor differences.
This patch set extends qcom_snd_parse_of() to handle links without DPCM,
so that we can use one common function for all (qcom) machine drivers.
Stephan Gerhold (7):
ASoC: qcom: Use devm for resource management
ASoC: qcom: common: Use snd_soc_dai_link_set_capabilities()
ASoC: q6afe: Remove unused q6afe_is_rx_port() function
ASoC: qcom: common: Support parsing links without DPCM
ASoC: qcom: common: Parse properties with "qcom," prefix
ASoC: qcom: apq8016_sbc: Use qcom_snd_parse_of()
ASoC: qcom: common: Avoid printing errors for -EPROBE_DEFER

With commit e2329eeba4 ("ASoC: soc-component: add soc_component_err()")
every error different for ENOTSUPP or EPROBE_DEFER will log an error.
However, as explained in snd_soc_get_dai_name(), this callback may error
to indicate that the DAI is not matched by the component tested. If the
device provides other components, those may still match. Logging an error
in this case is misleading.
Don't use soc_component_ret() in snd_soc_component_of_xlate_dai_name()
to avoid spamming the log.
