From f7a3c997af148b13a6225898c9bde1cb858924ba Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Wed, 27 Feb 2013 17:02:39 -0800 Subject: drivers/video/backlight/ams369fg06.c: make power_on() call optional This patch makes power_on() call optional. The voltage source can be provided to some boards using ams369fg06 panel, thus in this case, power on/off sequence is not necessary.
