These are v4 digital_mute() patch which adjusts
to atmel which had conflict on v3.
v3 -> v4
- tidyup for atmel which had conflict

Merge series "ASoC: merge .digital_mute() into .mute_stream()" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
These are v3 patch-set.
ALSA SoC has 2 mute callbacks (= .digital_mute(), .mute_stream()).
But the difference between these 2 are very small.
.digital_mute() is for Playback
.mute_stream() is for Playback/Capture
This patch-set adds new .no_capture_mute flag and emulate
.digital_mute() by .mute_stream().
v2 -> v3
- uses "xxx_mute_stream" for .mute_stream naming
if it was better
- removed verbose Cc email address

ASoC: soc-dai.c: add .no_capture_mute support
See include/linux/compiler_attributes.h:
/*
* Add the pseudo keyword 'fallthrough' so case statement blocks
* must end with any of these keywords:
* break;
* fallthrough;
* goto <label>;
* return [expression];
*
* gcc: https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html#Statement-Attributes
*/
-if __has_attribute(__fallthrough__)
- define fallthrough __attribute__((__fallthrough__))
-else
- define fallthrough do {} while (0) /* fallthrough */
-endif
The semi-colon is needed, to prevent the comment being parsed as part of the "if {...}" statement.
The warning looks like this:
seeed-voicecard/wm8960.c: In function ‘wm8960_hw_params’:
seeed-voicecard/wm8960.c:752:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
