Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Fixes a bootstrapping issue for some registers when a less commonly used method for register cache initialisation is used. Only affects a fairly small proportion of users that both don't use explicit register defaults and do use the cache. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Fix cache defaults initialization from raw cache defaults
