-Subject: [PATCH] video: bcm2708_fb: Disable FB if no displays found
-
-If the firmware hasn't detected a display, the driver would assume
-one display was available, but because it had failed to retrieve the
-display size it would try to allocate a zero-sized buffer.
-
-Avoid the allocation failure by bailing out early if no display is
-found.
