Pull regmap fixes from Mark Brown:
 "The most important fix here is for missing dropping of the RCU read
  lock when syncing maple tree register caches, the physical devices I
  have that use the code don't do any syncing so I'd only ever tested
  this with virtual devices and missed the fact that we need to drop the
  lock in order to write to buses that need to sleep.

  Otherwise there's a fix for an edge case when splitting up large batch
  writes which has been lurking for a long time, a check to make sure
  nobody writes new drivers with a bug that was found in several
  SoundWire drivers and a tweak to the way the new kunit tests are
  enabled to ensure they don't cause regmap to be enabled when it
  wouldn't otherwise be"
