The afe_priv->dai_priv[] is allocated when platform driver probe(), if it
failed, the ASoC platform driver probe() will return fail first.
Therefore, this is excessive judgment, and the condition will never be
established.

The functions related to SOF can be reused in different machine drivers,
such as mt8195 or mt8186, so extract the common code to avoid duplication.
Set mtk_soc_card_data which include machine private data and SOF private
data as card drvdata, then the difference between machine private can be
ignored such as mt8195_mt6359_priv or mt8186_mt6366_priv, at the same
time the SOF related code can be reused in different machine drivers.

The lockdep mechanism revealed an unbalanced unlocking on MT8186:
[ 2.993966] WARNING: bad unlock balance detected!

[ 2.994012] but there are no more locks to release!
The cause is that the mutex will be double unlocked if dai is unknown
during GPIO selection, and this patch fixes it.

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
Currently the set_fmt callback always passes clock provider/consumer
with respect to the CODEC. This made sense when the framework was
directly broken down into platforms and CODECs. However, as things
are now broken down into components which can be connected as either
the CPU or CODEC side of a DAI link it simplifies things if each
side of the link is just told if it is provider or consumer of the
clocks. Making this change allows us to remove one of the last parts
of the ASoC core that needs to know if a driver is a CODEC driver,
where it flips the clock format specifier if a CODEC driver is used on
the CPU side of a DAI link, as well as just being conceptually more
consistent with componentisation.
The basic idea of this patch chain is to change the set_fmt callback
from specifying if the CODEC is provider/consumer into directly
specifying if the component is provider/consumer. To do this we add
some new defines, and then to preserve bisectability, the migration is
done by adding a new callback, converting over all existing CPU side
drivers, converting the core, and then finally reverting back to the
old callback.
Converting the platform drivers makes sense as the existing defines
are from the perspective of the CODEC and there are more CODEC drivers
than platform drivers.
Obviously a fair amount of this patch chain I was only able to build
test, so any testing that can be done would be greatly appreciated.

This can probably wait for the next merge window, I found a number of

that the only really important issue found by cppcheck was on one of
my previous DPCM changes (submitted separately as a fix).

snd_soc_card_jack_new() allowed to create jack kcontrol without pins,
but did not create kcontrols. The jack would not have kcontrols if pins
were not going to be added.
This renames the old snd_soc_card_jack_new() to
snd_soc_card_jack_new_pins() for use when pins are provided or will be
added later. The new snd_soc_card_jack_new() appropriately creates a
jack for use without pins and adds a kcontrol.

The series reuses mt8192-mt6359-rt1015-rt5682.c for supporting machine
driver with rt1015p speaker amplifier and rt5682s headset codec.
Add support for using the rt5682s codec together with rt1015p on
mt8192-mt6359 machines. All configurations are shared with the rt5682
codec variant, so simply select the SND_SOC_RT5682S config to ensure the
codec is present and set the correct card name. The codec will be linked
to by pointing to it in the headset-codec property in the devicetree.
While at it, also create macros for the names of the different codec
variants supported by this driver, as well as rename occurrences of
rt1015p_rt5682 to rt1015p_rt5682x, since they are shared between rt5682
and rt5682s.
