Merge tag 'drm-fixes-for-v4.12-rc1' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie: "AMD, nouveau, one i915, and one EDID fix for v4.12-rc1 Some fixes that it would be good to have in rc1. It contains the i915 quiet fix that you reported. It also has an amdgpu fixes pull, with lots of ongoing work on Vega10 which is new in this kernel and is preliminary support so may have a fair bit of movement. Otherwise a few non-Vega10 AMD fixes, one EDID fix and some nouveau regression fixers" * tag 'drm-fixes-for-v4.12-rc1' of git://people.freedesktop.org/~airlied/linux: (144 commits) drm/i915: Make vblank evade warnings optional drm/nouveau/therm: remove ineffective workarounds for alarm bugs drm/nouveau/tmr: avoid processing completed alarms when adding a new one drm/nouveau/tmr: fix corruption of the pending list when rescheduling an alarm drm/nouveau/tmr: handle races with hw when updating the next alarm time drm/nouveau/tmr: ack interrupt before processing alarms drm/nouveau/core: fix static checker warning drm/nouveau/fb/ram/gf100-: remove 0x10f200 read drm/nouveau/kms/nv50: skip core channel cursor update on position-only changes drm/nouveau/kms/nv50: fix source-rect-only plane updates drm/nouveau/kms/nv50: remove pointless argument to window atomic_check_acquire() drm/amd/powerplay: refine pwm1_enable callback functions for CI. drm/amd/powerplay: refine pwm1_enable callback functions for vi. drm/amd/powerplay: refine pwm1_enable callback functions for Vega10. drm/amdgpu: refine amdgpu pwm1_enable sysfs interface. drm/amdgpu: add amd fan ctrl mode enums. drm/amd/powerplay: add more smu message on Vega10. drm/amdgpu: fix dependency issue drm/amd: fix init order of sched job drm/amdgpu: add some additional vega10 pci ids ...
