regulator: Fix the logic to ensure new voltage setting in valid range
I think this is a typo. To ensure new voltage setting won't greater than desc->max, the equation should be desc->min + desc->step * new_val <= desc->max. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org
