regmap: Allow regmap_update_bits() users to detect changes
Some users of regmap_update_bits() would like to be able to tell their users if they actually did an update so provide a variant which also returns a flag indicating if an update took place. We could return a tristate in the return value of regmap_update_bits() but this makes the API more cumbersome to use and doesn't fit with the general zero for success idiom we have. cherry-picked from main line commit 018690d33ecf4aa1eb1415e38c40e2b0b6c7808e Change-Id: I1b8d5dd436576f9238db89c61a6b8a6edd9d1151 Signed-off-by: Mark Brown <> Signed-off-by: Laxman Dewangan <> Reviewed-on: http://git-master/r/87571
