Pull regmap fixes from Mark Brown:
 "The biggest fix here is Lars-Peter's fix for custom locking callbacks
  which is pretty localised but important for those devices that use the
  feature.  Otherwise we've got a couple of fairly small cleanups which
  would have been sent sooner were it not for letting Lars-Peter's patch
  soak for a while"
