+ uxa: Check for DPMS off before scheduling a WAIT_ON_EVENT
+
+ Regression from commit 3f3bde4f0c72f6f31aae322bcdc20b95eade6631
+ Author: Chris Wilson <ch...@chris-wilson.co.uk>
+ Date: Thu May 24 11:58:46 2012 +0100
+
+ uxa: Only consider an output valid if the kernel reports it attached
+
+ When backporting from SNA, a key difference that UXA does not track DPMS
+ state in its enabled flag and that a DPMS off CRTC is still bound to the
+ fb. So we do need to rescan the outputs and check that we have a
+ connector enabled *and* the pipe is running prior to emitting a scanline
+ wait.
