Merge branch 'drm-armada-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-fixes
A range of fixes for the Armada DRM driver: - A missing wakeup could result in overlay frames being delayed, causing video playback to hiccup. - Avoid unmapping a dma-buf attachment which was never mapped - Fix the overlay when partially off the screen by switching to the drm_plane_helper_check_update() helper and using the calculated coordinates to set the start address. - Remove an incorrect assignment to crtc->mode - which should be the unadjusted mode. - Fix a missing call to drm_plane_cleanup() in the overlay code. * 'drm-armada-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: drm/armada: avoid saving the adjusted mode to crtc->mode drm/armada: fix overlay when partially off-screen drm/armada: convert overlay to use drm_plane_helper_check_update() drm/armada: fix gem object free after failed prime import drm/armada: fix incorrect overlay plane cleanup drm/armada: fix missing overlay wake-up
