      drm/virtio: fix an error code in virtio_gpu_init() · eb988a2e
      Dan Carpenter authored
      If devm_request_mem_region() fails this code currently returns success
      but it should return -EBUSY.

      drm/todo: Add entry for moving to dma_resv_lock · 5823cca3
      Daniel Vetter authored
      Requested by Thomas. I think it justifies a new level, since I tried
      to make some forward progress on this last summer, and gave up (for
      now). This is very tricky.
