2015-12-22ASoC: ssm2518: Use a signed return type for ssm2518_lookup_mcs()Markus Elfring
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.

2015-10-20ASoC: ssm2518: Drop .volatile_reg implementationAxel Lin
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.

Add OF match table to SSM2518 to allow direct matching without going through I2C subsystem. Signed-off-by: Ricard Wanderlof <ricardw@axis.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-07-15ASoC: drivers: Drop owner assignment from i2c_driverKrzysztof Kozlowski
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-05-04ASoC: ssm2518: Replace direct snd_soc_codec dapm field accessLars-Peter Clausen
The dapm field of the snd_soc_codec struct is eventually going to be removed, in preparation for this replace all manual access to codec->dapm.bias_level with snd_soc_codec_get_bias_level(). Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-04-27ASoC: Move bias level update to the coreLars-Peter Clausen
All drivers have the same line at the end of the set_bias_level callback to update the bias_level state. Move this update into snd_soc_dapm_force_bias_level() and remove them from the drivers. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-09-04ASoC: ssm2518: Cleanup manual bias level transitionsLars-Peter Clausen
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.

As SOC_ENUM_SINGLE_DECL() itself contains const modifier now, we can reduce const from its users. Signed-off-by: Takashi Iwai <tiwai@suse.de> Acked-by: Liam Girdwood <liam.r.girdwood@linux.intel.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-01-02ASoC: ssm2518: Fix off-by-one error by ffs()Takashi Iwai
ffs() returns the bit position from 1, while the ssm2158 driver code assumes it being 0-based. Also, the bit mask computation of the two channel slots are incorrect; it must have worked just casually.

2013-05-25ASoC: Add ssm2518 supportLars-Peter Clausen
