Merge tag 'drm-fixes-2019-07-26' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Daniel Vetter:
 "Dave seems to collect an entire streak of things happening, so again
  me typing pull summary.

  Nothing nefarious here, most of the fixes are for new stuff or things
  users won't see. The amd-display patches are a bit different, and very
  much look like they should have at least some cc: stable tags. Might
  be amd is a bit too comfortable with their internal tree and not
  enough looking at upstream. Dave&me are looking into this, in case
  something needs rectified with process here.

  Also no intel fixes pull, but intel CI is general become rather good,
  still I guess expect a notch more for -rc3.

  Summary:

  amdgpu:
   - fixes for (new in 5.3) hw support (vega20, navi)
   - disable RAS
   - lots of display fixes all over (audio, DSC, dongle, clock mgr)

  ttm:
   - fix dma_free_attrs calls to appease dma debugging

  msm:
   - fixes for dma-api, locking debug and compiler splats

  core:
   - fix cmdline mode to not apply rotation if not specified (new in 5.3)
   - compiler warn fix"
