Subject: [PATCH 01/56] regulator: Fix the logic to ensure new voltage setting
in valid range
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.
