regulator: Fix the logic to ensure new voltage setting in valid range 2012-05-12T16:32:17+00:00 Axel Lin axel.lin@gmail.com 2012-04-11T12:53:58+00:00 89ec66f87f76f389887b04a415f6dd53305bb9d0 commit f55205f4d4a8823a11bb8b37ef2ecbd78fb09463 upstream. 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.
