From eae745379d4c6453d8f8888a8003a1c1ebcfbbd3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C5=81ukasz=20Majewski?= Date: Mon, 24 Feb 2014 13:33:08 +0100 Subject: power: fix: Do not execute pmic command when not all necessary parameters are passed Lack of this check resulted in a data abort when CPU tried to execute the following command (without further mandatory input): 'pmic MAX77686_PMIC'. Only the 'pmic list' command requires one passed parameter. Other require at least two valid parameters for correct operation.
