e8e08c521d ASoC: tlv320aic32x4: Fix regmap range_min
range_min is the lowest address in the virtual register range. This is
the first register with address 0, not the first register of page 1.

Currently all writes to page 1 are mapped to page 0, so the codec fails
to operate.

6d0d5103bd ASoC: codec: tlv320aic32x4: Fix regmap range config
This codec driver fails to probe because it has a higher regmap
range_max value than max_register. This patch sets the range_max to the
max_register value as described in the for struct regmap_range_cfg:
"@range_max: Address of the highest register in virtual range."

002220a90d ASoC: dpcm: Allow PCMs to omit the set of supported formats
Allow PCMs that do not impose any restrictions on the supported formats to set
the formats field to 0, Instead of assuming that this means that the PCM does
not support any formats (which doesn't make much sense), assume that it supports
all formats. This brings the behavior of DPCM closer to that of non-DPCM.

14c3aa9839 ASoC: imx-spdif: Use snd-soc-dummy CODEC driver to link card
This is a quick fix for the below two issues when building spdif as modules.

1) If modprobing modules in order: (Step 1) snd-soc-fsl-spdif -> (Step 2)
snd-soc-imx-spdif -> (Step 3) snd-soc-spdif-tx/rx, we will fail to create
imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe
it again due to the execution platform_driver_unregister() in probe() when
meeting -EPROBE_DEFER at Step 2.

2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok",
'rmmod snd-soc-imx-spdif' would cause kernel dump with warning:
WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915 sysfs_hash_and_remove+0x84/0x90()
sysfs: can not remove 'dapm_widget', no directory
This should be caused by disordered resourse releasing of the whole link.
And trying to unregister the card and then CODEC dev can't fix this issue.

Thus this patch just provides a simple fix to these two bugs by using the
snd-soc-dummy in the core instead of seperate snd-soc-spdif-tx/rx so that
there's no need to handle the registering and unregistering of CODEC or
CODEC dai any more.

f52c919215 ASoC: davinci: Don't set unused struct snd_pcm_hardware fields
The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

4e3a99f5b0 ASoC: fsl_sai: Sort local variable in general way
Generally we would write code for local variable like:
static new_func()
{
	struct xxx *yyy;
	...
	int ret;
}

But this driver only follows this pattern for some functions, not all.
Thus this patch sorts the local variable in the general way.

190af12dad ASoC: fsl_sai: Make dev_err information neater
Since using dev_err() there's no need to mention SAI any more, it will
print the full name of the driver -- fsl_sai.
