Merge tag 'regmap-fix-v4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap fixes from Mark Brown: "A couple of small build fixes here, nothing major. The missing include is triggered in some configurations and the renaming of ret is defensive for the benefit of some drivers people are in the process of mainlining" * tag 'regmap-fix-v4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Rename ret variable in regmap_read_poll_timeout regmap: include <linux/delay.h> from include/linux/regmap.h
