Subject: [PATCH 09/22] backlight: da903x_bl: use devm_backlight_device_register()
Date: Tue, 24 Sep 2013 18:11:32 +0900	[thread overview]
Message-ID: <004f01ceb906$0f824120$2e86c360$%han@samsung.com> (raw)
In-Reply-To: <004701ceb905$03e8da50$0bba8ef0$%han@samsung.com>

Use devm_backlight_device_register() to make cleanup paths simpler,
and remove unnecessary remove().
