[PATCH] rivafb/nvidiafb: race between register_framebuffer and *_bl_init
Since we now use the generic backlight infrastructure, I think we need to call rivafb_bl_init before calling register_framebuffer since otherwise rivafb_bl_init might race with the framebuffer layer already opening the device and setting up the video mode. In this case we might end up with a not yet fully intialized backlight (info->bl_dev still NULL) when calling riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel dies without any further notice during boot. This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb would be affected too - I can fix that too but don't have any hardware to test this on. Cc: "Antonino A.
