Merge tag 'drm-fixes-for-v4.13-rc1' of git://people.freedesktop.org/~airlied/linux
Pull more drm updates from Dave Airlie: "i915, amd and some core fixes + mediatek color support. Some fixes tree came in since the main pull request for rc1, primarily i915 and drm-misc and one amd fix. The drm core vblank regression fix is probably the most important thing. I've also added the mediatek feature pull, it wasn't that big and didn't look like it would have any impact outside of mediatek, in fact it looks to just be a single feature, and some cleanups" * tag 'drm-fixes-for-v4.13-rc1' of git://people.freedesktop.org/~airlied/linux: (31 commits) drm/i915: Make DP-MST connector info work drm/i915/gvt: Use fence error from GVT request for workload status drm/i915/gvt: remove scheduler_mutex in per-engine workload_thread drm/i915/gvt: Revert "drm/i915/gvt: Fix possible recursive locking issue" drm/i915/gvt: Audit the command buffer address drm/i915/gvt: Fix a memory leak in intel_gvt_init_gtt() drm/rockchip: fix NULL check on devm_kzalloc() return value drm/i915/fbdev: Check for existence of ifbdev->vma before operations drm/radeon: Fix eDP for single-display iMac10,1 (v2) drm/i915: Hold RPM wakelock while initializing OA buffer drm/i915/cnl: Fix the CURSOR_COEFF_MASK used in DDI Vswing Programming drm/i915/cfl: Fix Workarounds. drm/i915: Avoid undefined behaviour of "u32 >> 32" drm/i915: reintroduce VLV/CHV PFI programming power domain workaround drm/i915: Fix an error checking test drm/i915: Disable MSI for all pre-gen5 drm/atomic: Add missing drm_atomic_state_clear to atomic_remove_fb drm: vblank: Fix vblank timestamp update drm/i915/gvt: Make function dpy_reg_mmio_readx safe drm/mediatek: separate color module to fixup error memory reallocation ...
