Merge tag 'drm-fixes-2020-03-20' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie: "Hope you are well hiding out above the garage. A few amdgpu changes but nothing too major. I've had a wisdom tooth out this week so haven't been to on top of things, but all seems good. core: - fix lease warning i915: - Track active elements during dequeue - Fix failure to handle all MCR ranges - Revert unnecessary workaround amdgpu: - Pageflip fix - VCN clockgating fixes - GPR debugfs fix for umr - GPU reset fix - eDP fix for MBP - DCN2.x fix dw-hdmi: - fix AVI frame colorimetry komeda: - fix compiler warning bochs: - downgrade a binding failure to a warning" * tag 'drm-fixes-2020-03-20' of git://anongit.freedesktop.org/drm/drm: drm/amd/display: Fix pageflip event race condition for DCN. drm/amdgpu: fix typo for vcn2.5/jpeg2.5 idle check drm/amdgpu: fix typo for vcn2/jpeg2 idle check drm/amdgpu: fix typo for vcn1 idle check drm/lease: fix WARNING in idr_destroy drm/i915: Handle all MCR ranges Revert "drm/i915/tgl: Add extra hdc flush workaround" drm/i915/execlists: Track active elements during dequeue drm/bochs: downgrade pci_request_region failure from error to warning drm/amd/display: Add link_rate quirk for Apple 15" MBP 2017 drm/amdgpu: add fbdev suspend/resume on gpu reset drm/amd/amdgpu: Fix GPR read from debugfs (v2) drm/amd/display: fix typos for dcn20_funcs and dcn21_funcs struct drm/komeda: mark PM functions as __maybe_unused drm/bridge: dw-hdmi: fix AVI frame colorimetry
