Subject: [PATCH 10/14] backlight: kb3886_bl: convert kb3886bl to dev_pm_ops
Date: Tue, 12 Mar 2013 14:52:20 +0900 [thread overview]
Message-ID: <004701ce1ee5$c321f650$4965e2f0$%han@samsung.com> (raw)
In-Reply-To: <003e01ce1ee5$4897e020$d9c7a060$%han@samsung.com>
Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management.
