In the case where __lpass_get_dmactl_handle is called and the driver
id dai_id is invalid the pointer dmactl is not being assigned a value,
and dmactl contains a garbage value since it has not been initialized
and so the null check may not work. Fix this to initialize dmactl to
NULL. One could argue that modern compilers will set this to zero, but
it is useful to keep this initialized as per the same way in functions
__lpass_platform_codec_intf_init and lpass_cdc_dma_daiops_hw_params.
Cleans up clang scan build warning:
sound/soc/qcom/lpass-cdc-dma.c:275:7: warning: Branch condition
evaluates to a garbage value [core.uninitialized.Branch]

Merge series from Rob Herring <robh@kernel.org>:
This is a series is part of ongoing clean-ups related to device
matching and DT related implicit includes. Essentially of_device.h has
a bunch of implicit includes and generally isn't needed any nore except
for of_match_device(). As we also generally want to get rid of
of_match_device() as well, I've done that so we're not updating the
includes twice.

Few units use qcom,lpass.h binding headers but they rely on them being
included through a different header. Make the usage explicit which
allows easier to find the users of a header.

'struct lpass_variant' is used for driver match data which is supposed to
be constant. It's not modified anywhere, so it's just a matter of adding
'const' everywhere.

ASoC is now unified asoc_xxx() into snd_soc_xxx().
This patch convert asoc_xxx() to snd_soc_xxx().
