Hello Felipe, While testing your 'next' branch merged with today's next I got some new warnings, caused by a recently introduced __must_check in: c8801a8 regulator: core: Mark all get and enable calls as __must_check These patches introduces a check for regulator_enable() return value in all three affected USB phy drivers, and issue a dev_err() in case it fails. TWL4030 and TWL6030 patches has been build-tested only.
