fix-backlight-too-early.patch
This moves the backlight init to right before the backlight device init
during the jbt6k74 probe callback... it guarantees video is up and the lcm
is configured before we bring up backlight and so removes the white flash
during boot, the all-black framebuffer is instead shown smoothly and
cleanly.
