From 1941e03299bc5a2cae729d70bc80560546542697 Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Wed, 19 Jun 2013 10:07:14 +1000 Subject: [PATCH] backlight: convert from legacy pm ops to dev_pm_ops Convert drivers/video/backlight/class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, backlight class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the backlight class.
