Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie: "A smattering of fixes, mgag200: don't accept modes that aren't aligned properly as hw can't do it i915: two regression fixes radeon: one query to allow userspace fixes one oops fixer for older hw with new options enabled" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: drm/radeon: don't probe MST on hw we don't support it on drm/radeon: Add RADEON_INFO_VA_UNMAP_WORKING query drm/mgag200: Reject non-character-cell-aligned mode widths Revert "drm/i915: Don't skip request retirement if the active list is empty" drm/i915: Always reset vma->ggtt_view.pages cache on unbinding
