Merge tag 'drm-fixes-2019-11-15' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie: "Here is this weeks non-intel hw vuln fixes pull. Three drivers, all small fixes. i915: - MOCS table fixes for EHL and TGL - Update Display's rawclock on resume - GVT's dmabuf reference drop fix amdgpu: - Fix a potential crash in firmware parsing sun4i: - One fix to the dotclock dividers range for sun4i" * tag 'drm-fixes-2019-11-15' of git://anongit.freedesktop.org/drm/drm: drm/amdgpu: fix null pointer deref in firmware header printing drm/i915/tgl: MOCS table update Revert "drm/i915/ehl: Update MOCS table for EHL" drm/sun4i: tcon: Set min division of TCON0_DCLK to 1. drm/i915: update rawclk also on resume drm/i915/gvt: fix dropping obj reference twice
