df561f6688 treewide: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

ASoC: rockchip: Fix a reference count leak.
Calling pm_runtime_get_sync increments the counter even in case of
failure, causing incorrect ref count if pm_runtime_put is not called in
error handling paths. Call pm_runtime_put if pm_runtime_get_sync fails.

ASoC: rockchip: pdm: Correct PDM_CTRL0 reg value
This patch fix the wrong reg value for rk322x/rk322xh,
cuz there is no STORE JUSTIFIED MODE on it.

on rk322x/rk322xh, the same bit means PDM_MODE/RESERVED,
if the bit is set to RESERVED, the controller will not work.

a snd_soc_dai_driver structure, which is const.  Thus, the
snd_soc_dai_ops structures can be const too.

fc05a5b222 ASoC: rockchip: add support for pdm controller
The Pulse Density Modulation Interface Controller (PDMC) is
a PDM interface controller and decoder that support PDM format.
It integrates a clock generator driving the PDM microphone
and embeds filters which decimate the incoming bit stream to
obtain most common audio rates.
