[v5,0/6] drm/qxl: fix driver shutdown issues.

Message

Almost there.  Still getting this on driver unbind:

   kobject: '(null)' ((____ptrval____)): is not initialized, yet kobject_put(=
) is being called
   [ ... ]
   Call Trace:
    ttm_device_fini+0x133/0x1b0 [ttm]
    qxl_ttm_fini+0x2f/0x40 [qxl]
    qxl_device_fini+0x88/0x120 [qxl]
    drm_minor_release+0x3d/0x60

but I don't think this is the qxl driver's fault.

v5:
 - add release_event wait queue.
 - also cleanup qxl_fence_wait().

Gerd Hoffmann (6):
  drm/qxl: use drmm_mode_config_init
  drm/qxl: unpin release objects
  drm/qxl: release shadow on shutdown
  drm/qxl: handle shadow in primary destroy
  drm/qxl: properly free qxl releases
  drm/qxl: simplify qxl_fence_wait
