[PATCH RESEND 11/13] omapfb: panel-lgphilips-lb035q02: remove backlight GPIO handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



With f048e8c1d169 ("omapfb: panel-lgphilips-lb035q02: Remove legacy boot
support") it is no longer possible to specify GPIO to control the
backlight. Remove code trying to request and toggle it.
