[Intel-gfx] [PATCH] Set tv format property if output crtc is NULL

[ling.ma at intel.com]

When TV is not connected and X start, after plugging TV cable again,
system will crash because output crtc is NULL. This patch will return,
do not handle crtc immediately, meanwhile set value will be effective
until user really enable output by xrandr command.
