Message-Id: <20120518211600.286013626@linuxfoundation.org> Date: Fri, 18 May 2012 14:16:08 -0700 From: Greg KH <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Axel Lin <axel.lin@...il.com>, Mark Brown <broonie@...nsource.wolfsonmicro.com> Subject: [ 09/54] regulator: Fix the logic to ensure new voltage setting in valid range 3.0-stable review patch. If anyone has any objections, please let me know. ------------------ From: Axel Lin <axel.lin@...il.com> 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.
