commit fe1cf74897f740ab3e31733649a435d1a9353e09
Author: James Simmons <jsimm...@infradead.org>
Date: Sat Mar 30 18:13:29 2013 -0400
Another IRQ issue. This time it is with vblank irq happening when nothing
is mapped to the crtc. To handle this a crtc disable function is introduce that
turns off the vbl, cursor, and power downs the crtc not in use.
