[alsa-devel] [PATCH 1/5] ASoC: Remove support for reg_access_defaults
No users of reg_access_defaults are left and new drivers are going to use regmap for this, so support for it can be removed.

reg_def_copy was introduced in commit 3335ddca ("ASoC: soc-cache: Use reg_def_copy instead of reg_cache_default") to keep a copy of the register defaults around in case the register defaults where placed in the __devinitdata section. With the __devinitdata section gone we effectivly keep the same data around twice. This patch removes reg_def_copy and uses reg_cache_default directly instead.

The reg_size field is calculated in snd_soc_register_codec() and then used exactly once in snd_soc_flat_cache_init(). Since it is calculated based on other fields from the codec struct just move the calculation to snd_soc_flat_cache_init() and remove the 'reg_size' field from the codec struct.

The only cache type left is the flat cache and new other cache types won't be added since new drivers are supposed to use regmap directly for IO and caching. This patch removes the snd_soc_cache_ops indirection that was added to support multiple cache types and modifies the code to always use the flat cache directly.
