> Subject: [PATCH] backlight: Set backlight type and max_brightness before
> backlights are registered
> 
> 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.
