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
