It seems patches 1 and 2 are subsumed by Axel Lin's
d04156bca629740a661fd0738cd69ba1f08b2b20 (regulator: tps65910: Add
missing breaks in switch/case), but this one was not marked for stable
even though it fixes a regression for tps65910 devices.

I'll send an updated patch 3 in a minute.

Thanks,
Johan
