From ae3e101286df40cdde49c4737e2868289ed7f35b Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Thu, 12 Sep 2013 09:38:12 +0800 Subject: [PATCH] regulator: palmas: Remove wrong comment for the equation calculating num_voltages Current equation on the comment is wrong. For linear mapping starting from 0, the equation is (maxV-minV)/stepV + 1. Since the linear mapping for PALMAS is not all starting from 0, the equation on the comment is not useful and misleading. Thus remove it.
