Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie: "Bit late with these, was under the weather for a a few days, nothing too crazy: Some radeon regression fixes, one intel regression fix, and one fix to avoid a warn with i915 when used with dma-buf" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: drm/i915: unpin backing storage in dmabuf_unmap drm/radeon: fix WREG32_OR macro setting bits in a register drm/radeon/r7xx: fix copy paste typo in golden register setup drm/i915: Don't deref pipe->cpu_transcoder in the hangcheck code drm/radeon: fix UVD message buffer validation
