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." * tag 'regmap-v3.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Back out work buffer fix
