Merge branch 'for-linus' of git://opensource.wolfsonmicro.com/regmap
* 'for-linus' of git://opensource.wolfsonmicro.com/regmap: (62 commits) mfd: Enable rbtree cache for wm831x devices regmap: Support some block operations on cached devices regmap: Allow caches for devices with no defaults regmap: Ensure rbtree syncs registers set to zero properly regmap: Allow rbtree to cache zero default values regmap: Warn on raw I/O as well as bulk reads that bypass cache regmap: Return a sensible error code if we fail to read the cache regmap: Use bsearch() to search the register defaults regmap: Fix doc comment regmap: Optimize the lookup path to use binary search regmap: Ensure we scream if we enable cache bypass/only at the same time regmap: Implement regcache_cache_bypass helper function regmap: Save/restore the bypass state upon syncing regmap: Lock the sync path, ensure we use the lockless _regmap_write() regmap: Fix apostrophe usage regmap: Make _regmap_write() global regmap: Fix lock used for regcache_cache_only() regmap: Grab the lock in regcache_cache_only() regmap: Modify map->cache_bypass directly regmap: Fix regcache_sync generic implementation ...
