Subject: [PATCH] Input: xpad - use LED API when identifying wireless controllers
Date: Wed, 16 Dec 2015 14:44:08 -0800	[thread overview]
Message-ID: <20151216224408.GA14261@dtor-ws> (raw)

When lighting up the segment identifying wireless controller, Instead of
sending command directly to the controller, let's do it via LED API (usinf
led_set_brightness) so that LED object state is in sync with controller
state and we'll light up the correct segment on resume as well.
