* ASoC: codecs: add const to snd_soc_codec_driver structuresBhumika Goyal2017-08-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Declare snd_soc_codec_driver structures as const as they are only passed as an argument to the function snd_soc_register_codec. This argument is of type const, so declare the structures with this property as const. In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in a copy operation along with getting passed to snd_soc_register_codec. So, it can be made const too. Done using Coccinelle: @match disable optional_qualifier@ identifier s; position p; @@ static struct snd_soc_codec_driver s@p={...}; @good1@ identifier match.s; position p; @@ snd_soc_register_codec(...,&s@p,...) @bad@ identifier match.s; position p!={match.p,good1.p}; @@ s@p @depends on !bad disable optional_qualifier@ identifier match.s; @@ static +const struct snd_soc_codec_driver s={...}; Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: codec duplicated callback function goes to component on ssm2518Kuninori Morimoto2016-08-081-6/+8
| | | | | | | | | | codec driver and component driver has duplicated callback functions, and codec side functions are just copied to component side when register timing. This was quick-hack, but no longer needed. This patch moves these functions from codec driver to component driver.

* ASoC: ssm2518: Use a signed return type for ssm2518_lookup_mcs()Markus Elfring2015-12-231-1/+1
| | | | | | | | | | | The return type "unsigned int" was used by the ssm2518_lookup_mcs() function even though it will eventually return a negative error code. Improve this implementation detail by deletion of the type modifier then. This issue was detected by using the Coccinelle software.

* ASoC: ssm2518: Drop .volatile_reg implementationAxel Lin2015-10-201-6/+0
| | | | | | | | | | The implementation of ssm2518_register_volatile always returns false, this behavior is the same as no .volatile_reg callback implementation when cache_type != REGCACHE_NONE.

* ASoC: ssm2518: Cleanup manual bias level transitionsLars-Peter Clausen2014-09-041-13/+0
| | | | | | | | | | | | Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_OFF at the end of CODEC probe() can also be removed as the CODEC is already in OFF state at this point.
