Subject: [PATCH] backlight: da903x_bl: switch to using SIMPLE_DEV_PM_OPS
Date: Tue, 12 Mar 2013 14:48:16 +0900 [thread overview]
Message-ID: <003d01ce1ee5$316a57c0$943f0740$%han@samsung.com> (raw)
This reduces #ifdefs in the code. Also, CONFIG_PM_SLEEP is used
to avoid warnings of unused functions if CONFIG_PM_SLEEP is not
defined.
