Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm update from Dave Airlie: "Exynos and Radeon mostly, with a dma-buf and ttm fix thrown in. It's a bit big but its mostly exynos license fix ups and I'd rather not hold those up since its legally stuff. Radeon has a couple of fixes from dma engine work, TTM is just a locking fix, and dma-buf fix has been hanging around and I finally got a chance to review it." * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (30 commits) drm/ttm: fix fence locking in ttm_buffer_object_transfer drm/prime: drop reference on imported dma-buf come from gem drm/radeon: add quirk for d3 delay during switcheroo poweron for apple macbooks drm/exynos: move finish page flip to a common place drm/exynos: fimd: modify condition in fimd resume drm/radeon: fix DMA CS parser for r6xx linear copy packet drm/radeon: split r6xx and r7xx copy_dma functions drm/exynos: Use devm_clk_get in exynos_drm_gsc.c drm/exynos: Remove redundant NULL check in exynos_drm_gsc.c drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_gsc.c drm/exynos: Use devm_clk_get in exynos_drm_rotator.c drm/exynos: Remove redundant NULL check in exynos_drm_rotator.c drm/exynos: Remove unnecessary devm_* freeing APIs in exynos_drm_rotator.c drm/exynos: Use devm_clk_get in exynos_drm_fimc.c drm/exynos: Remove redundant NULL check drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_fimc.c drm/exynos: Use devm_kzalloc in exynos_drm_ipp.c drm/exynos: fix gem buffer allocation type checking drm/exynos: remove needless parenthesis. drm/exynos: fix incorrect interrupt induced by m2m operation. ...
