ASoC: remove codec reg_cache

2018-05-09T09:38:23+00:00

Codec reg_cache is legacy feature, almost all driver are now using common regmap, and very few driver had been used this legacy feature. Because of this background, it is now implemented on each driver internally now. So now, no one is using codec reg_cache. Let's remove it.

ASoC: Remove snd_soc_cache_sync() implementation

2014-11-09T09:06:30+00:00

This function has no more non regmap user, which means we can remove the implementation of the function and associated functions and structure fields. For convenience we keep a static inline version of the function that forwards calls to regcache_sync() unconditionally. Signed-off-by: Lars-Peter Clausen Signed-off-by: Mark Brown

ASoC: Forward calls to snd_soc_cache_sync() to regcache_sync()

2014-11-09T09:06:30+00:00

For convenience for drivers that do not want to keep their own pointer to regmap struct around forward calls to snd_soc_cache_sync() to regcache_sync() if the driver is using regmap. This is similar to what we do for snd_soc_read()/snd_soc_write(). This patch also fixes drivers which already have been converted to regmap, but still use snd_soc_cache_sync() for trying to the sync the cache.

ASoC: Move name and id from CODEC/platform to component

2014-06-21T20:04:24+00:00

The component struct already has a name and id field which are initialized to the same values as the same fields in the CODEC and platform structs. So remove them from the CODEC and platform structs and used the ones from the component struct instead. Signed-off-by: Lars-Peter Clausen Signed-off-by: Mark Brown

ASoC: cache: Fix error code when not using ASoC level cache

2014-06-02T15:08:21+00:00

It is not an error to have no cache so we shouldn't return an error code and cause our callers to fail, just silently do nothing instead. Thanks to Jarkko for identify the problematic commit. Reported-by: Jarkko Nikula Reported-by: Fabio Estevam Signed-off-by: Mark Brown

ASoC: cache: Fix possible ZERO_SIZE_PTR pointer dereferencing error.

2014-06-01T19:02:17+00:00

Since we cannot make sure the 'reg_size' will always be none zero here, and then if 'reg_size' equals to zero, the kzalloc() will return ZERO_SIZE_PTR, which equals to ((void *)16). So this patch fix this with just doing the 'reg_size' zero check before calling kzalloc(). Signed-off-by: Xiubo Li Signed-off-by: Mark Brown

ASoC: Remove IO register modifier callbacks

2014-04-14T16:22:43+00:00

There are no ASoC drivers left that use them and new drivers are supposed to use regmap for this. Signed-off-by: Lars-Peter Clausen Signed-off-by: Mark Brown

ASoC: cache: Do the codec->reg_cache zero pionter check

2014-03-04T04:32:19+00:00

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.

ASoC: Replace BUG() with WARN()

2013-11-07T19:55:21+00:00

BUG() used in the driver is just to spit the stack trace on buggy points, not really needed to stop the whole operation. For that purpose, it'd be more convenient to use WARN() instead with more error information. Signed-off-by: Takashi Iwai Signed-off-by: Mark Brown
