That way the kernel has a known link between the LCD panel and the
backlight and eveything should work smoothly :) I suggest to wait
for it to land and carry any Droid 4 specific hacks downstream until
that happens. This will also remove the bogus DSI backlight from sysfs.
Without the backlight reference the panel driver assumes, that native
DSI backlight is used.
