Also do this if we've got get_voltage_sel() [Rewite commit message for clarity -- broonie] Signed-off-by: Tirupathi Reddy Signed-off-by: Mark Brown --- diff --git a/drivers/regulator/core.c b/drivers/regulator/core.c index c0d9ae8d0860..9fecbd4e3546 100644 --- a/drivers/regulator/core.c +++ b/drivers/regulator/core.c @@ -2938,7 +2938,8 @@ static int regulator_set_voltage_unlocked(struct regulator *regulator, if (rdev->supply && regulator_ops_is_valid(rdev->supply->rdev, REGULATOR_CHANGE_VOLTAGE) && - (rdev->desc->min_dropout_uV || !rdev->desc->ops->get_voltage)) { + (rdev->desc->min_dropout_uV || !(rdev->desc->ops->get_voltage || + rdev->desc->ops->get_voltage_sel))) { int current_supply_uV; int selector;
