For the snd_soc_cache_init(), the reg_size maybe zero and then the value
of codec->reg_cache, which is alloced via kzalloc, maybe equal to
ZERO_SIZE_PTR. If the reg parameter of snd_soc_cache_write() is large enough,
the cache[idx] = val maybe cause the kernel crash...
So this patch fix this via doing the zero pionter check of it.

Since 3.14-rc1 only DT boot has been supported on N810, so this
file fails to init. Make a minimal fix to retain functionality.
This file should be properly converted to DT in longer term.
There seems to be still other unresolved issues with N810 audio support,
but this patch is needed at minimum as otherwise the machine driver
probing would completely fail.

rsnd_adg_ssi_ws_timing_gen2() returns SSI WS timing,
and it used "mod" as parameter.
but, this "mod" is sometimes not ssi mod.

struct rsnd_dai_stream used list for mod list.
It added only odd flexibility to current driver, and

Current rsnd SSIU/SSI/SCU/SRU path is set
when playback/capture starts up.
But it is meaningless method, since the path is based
on platform and can be set in probe() timing.
This patch sets the path on probe() timing.

With the ongoing component-ization of the ASoC framework and the continuing
migration to using regmap for IO the control_data field of the snd_soc_codec
struct will eventually be removed. Prepare the wm5192, wm5110 and wm8997
drivers for this by using arizona->regmap instead of accessing the CODEC's
control_data field.

The wm8763 driver uses regmap for IO which means that codec->cache_sync is not
used. The line was added in commit d3398ff ('ASoC: Convert WM8753 to direct
regmap API usage'). Presumably this was meant to be regcache_mark_dirty(), but
since we already call regcache_mark_dirty() in the core when suspending the
CODEC it is safe to just remove the line.

The new sequence ensure that dapm_pre_sequence_async work on
the card before all codecs and dapm_post_sequence_async work
on the card after all codecs.
So the machine driver could utilize the determinate sequence

When calling {corgi,poodle,spitz}_ext_control() from the startup callback we
pass the CODEC's DAPM context instead of the card's DAPM context. This is not a
problem per se since all the DAPM functions in ext_control() fallback to widgets
from other DAPM contexts, but passing the card's context is more consistent.
