Merge tag 'regmap-v3.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap fixes from Mark Brown:
"A small collection of fixes. The most important ones are those from
Stephen and Lars-Peter both of which fix cache issues that have been
lurking for a while but not manifesting noticably enough for anyone to
report them."
* tag 'regmap-v3.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
regmap: async: Add missing return
regmap: don't corrupt work buffer in _regmap_raw_write()
regmap: cache Fix regcache-rbtree sync
regmap: Initialize `map->debugfs' before regcache
