Merge tag 'regmap-v3.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap revert from Mark Brown:
"regmap: Back out work buffer fix
This reverts commit bc8ce4 (regmap: don't corrupt work buffer in
_regmap_raw_write()) since it turns out that it can cause issues when
taken in isolation from the other changes in -next that lead to its
discovery. On the basis that nobody noticed the problems for quite
some time without that subsequent work let's drop it from v3.9."
