ASoC: Fixes for v5.3

A relatively large batch of mostly unremarkable fixes here, a couple of
small core fixes for fairly obscure issues, more comment/email updates
with no code impact than usual and a bunch of small driver fixes.

The support for new sample rates in the max98373 driver is a fix for the
fact that the driver declared support for those rates but would in fact
return an error if these rates were selected.

ASoC: audio-graph-card: add missing const at graph_get_dai_id()

2019-07-11T11:27:29+00:00

commit c152f8491a8d9 ("ASoC: audio-graph-card: fix an use-after-free in
graph_get_dai_id()") fixups use-after-free issue,
but, it need to use "const" for reg. This patch adds it.

We will have below without this patch

LINUX/sound/soc/generic/audio-graph-card.c: In function 'graph_get_dai_id':
LINUX/sound/soc/generic/audio-graph-card.c:87:7: warning: assignment discards\
 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]

ASoC: audio-graph-card: fix an use-after-free in graph_get_dai_id()

2019-07-10T15:33:57+00:00

After calling of_node_put() on the node variable, it is still being
used, which may result in use-after-free.
Fix this issue by calling of_node_put() after the last usage.

ASoC: simple-card-utils: care no Platform for DPCM

2019-07-10T15:25:45+00:00

commit 34614739988ad ("ASoC: soc-core: support dai_link with
platforms_num != 1") supports multi Platform, and
commit 9f3eb91753451 ("ASoC: simple-card-utils: consider CPU-Platform
possibility") removed no Platform from simple-card.

Multi Platform is now checking both Platform name/of_node are NULL case.
But in normal case, DPCM be doesn't have Platform.

asoc_simple_canonicalize_platform() try to use CPU of_node
to Platform (This is needed for DMAEngine platform case),
but it still might be NULL at DPCM be.

This patch try to use no Platform after that if Platform of_node
is still NULL. It can't probe without this patch.
