From ba3601a99fde549707f5f869c977c0072fee04e1 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 29 Apr 2013 16:17:25 -0700 Subject: [PATCH] drivers/video/backlight/ams369fg06.c: convert ams369fg06 to dev_pm_ops Instead of using legacy suspend/resume methods, using newer dev_pm_ops structure allows better control over power management.
