Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"One nouveau deadlock fix, one qxl irq handling fix, and a set of
radeon pageflipping changes that fix regressions in pageflipping since
-rc1 along with a leak and backlight fix.
The pageflipping fixes are a bit bigger than I'd like, but there has
been a few people focused on testing them"
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/radeon: Make classic pageflip completion path less racy.
drm/radeon: Add missing vblank_put in pageflip ioctl error path.
drm/radeon: Remove redundant fence unref in pageflip path.
drm/radeon: Complete page flip even if waiting on the BO fence fails
drm/radeon: Move pinning the BO back to radeon_crtc_page_flip()
drm/radeon: Prevent too early kms-pageflips triggered by vblank.
drm/radeon: set default bl level to something reasonable
drm/radeon: avoid leaking edid data
drm/qxl: return IRQ_NONE if it was not our irq
drm/nouveau/therm: fix a potential deadlock in the therm monitoring code
