With the current state of code, we would endup with something like
below in /proc/asound/cards for 2 machines based on this driver.
Machine 1:
0 [DB845c ]: DB845c - DB845c
DB845c
Machine 2:
0 [LenovoYOGAC6301]: Lenovo-YOGA-C63 - Lenovo-YOGA-C630-13Q50
LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216
This is not very UCM friendly both w.r.t to common up configs and
card identification, and UCM2 became totally not usefull with just
one ucm sdm845.conf for two machines which have different setups
w.r.t HDMI and other dais.
Reasons for such thing is partly because Qualcomm machine drivers never
cared to set driver_name.
This patch sets up driver name for the this driver to sort out the
UCM integration issues!
after this patch contents of /proc/asound/cards:
Machine 1:
0 [DB845c ]: sdm845 - DB845c
DB845c
Machine 2:
0 [LenovoYOGAC6301]: sdm845 - Lenovo-YOGA-C630-13Q50
LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216
with this its possible to align with what UCM2 expects and we can have
sdm845/DB845.conf
sdm845/LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216.conf
... for board variants. This should scale much better!

This warning was introduced in
commit 81033c6b58 ("ALSA: core: Warn on empty module").
It looks like we are supposed to set card->owner to THIS_MODULE.
Fix this for all the qcom ASoC drivers.

Headset codec is connected over PRIMARY_MI2S interface. Call
set_jack for codec associated with Primary Mi2s interface.
Also, set_jack to NULL when jack is freed.

The snd_soc_ops structure can be const as it is only stored in the
ops field of a snd_soc_dai_link structure and this field is const.

Remove auto rebinding support, as component framework can deadlock
in few usecases if we are trying to add new/remove component within
a bind/unbind callbacks.
Card rebinding is ASoC core feature so all the previous component
framework stuff in q6dsp remains removed.
