Subject: [PATCH 0/3] regmap: Add interface for checking if a register is
 cached

HDA has a use case for checking if a register is present in the cache
which it awkwardly open codes with use of _cache_only() and a read,
provide a direct API for this.

Mark Brown (3):
      regmap: Let users check if a register is cached
      regmap: Provide test for regcache_reg_present()
      ALSA: hda: Use regcache_reg_cached() rather than open coding
