Subject: [PATCH] backlight: Set backlight type and max_brightness before backlights are registered
Date: Tue, 05 Jul 2011 12:37:49 +0800 [thread overview]
Message-ID: <1309840669.6072.3.camel@phoenix> (raw)
Since commit a19a6ee "backlight: Allow properties to be passed at registration"
and commit bb7ca74 "backlight: add backlight type",
we can set backlight type and max_brightness before backlights are registered.
Some newly added drivers did not set it properly, let's fix it.
