commit: f55205f4d4a8823a11bb8b37ef2ecbd78fb09463 From: Axel Lin <[email protected]> Date: Wed, 11 Apr 2012 20:53:58 +0800 Subject: 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.
