Merge tag 'regmap-v3.14-rc4' into regmap-linus
regmap: Fix for v3.14
One fix here, for syncing the last register in a cache block when the
register map has a stride. This is a fairly unusual hardware
configuration and the fact that it only affects the last register in a
block makes the issue rarer still.
