Merge tag 'drm-fixes-for-v4.16-rc7' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie: "A bunch of fixes all over the place (core, i915, amdgpu, imx, sun4i, ast, tegra, vmwgfx), nothing too serious or worrying at this stage. - one uapi fix to stop multi-planar images with getfb - Sun4i error path and clock fixes - udl driver mmap offset fix - i915 DP MST and GPU reset fixes - vmwgfx mutex and black screen fixes - imx array underflow fix and vblank fix - amdgpu: display fixes - exynos devicetree fix - ast mode fix" * tag 'drm-fixes-for-v4.16-rc7' of git://people.freedesktop.org/~airlied/linux: (29 commits) drm/ast: Fixed 1280x800 Display Issue drm: udl: Properly check framebuffer mmap offsets drm/i915: Specify which engines to reset following semaphore/event lockups drm/vmwgfx: Fix a destoy-while-held mutex problem. drm/vmwgfx: Fix black screen and device errors when running without fbdev drm: Reject getfb for multi-plane framebuffers drm/amd/display: Add one to EDID's audio channel count when passing to DC drm/amd/display: We shouldn't set format_default on plane as atomic driver drm/amd/display: Fix FMT truncation programming drm/amd/display: Allow truncation to 10 bits drm/sun4i: hdmi: Fix another error handling path in 'sun4i_hdmi_bind()' drm/sun4i: hdmi: Fix an error handling path in 'sun4i_hdmi_bind()' drm/i915/dp: Write to SET_POWER dpcd to enable MST hub. drm/amd/display: fix dereferencing possible ERR_PTR() drm/amd/display: Refine disable VGA drm/tegra: Shutdown on driver unbind drm/tegra: dsi: Don't disable regulator on ->exit() drm/tegra: dc: Detach IOMMU group from domain only once dt-bindings: exynos: Document #sound-dai-cells property of the HDMI node drm/imx: move arming of the vblank event to atomic_flush ...
