Pull drm fixes from Dave Airlie:
 "Live from my friend's couch in Barcelona, latest round of drm fixes.

  The command line parser regression fixes look a bit larger because
  they come with selftests included for the bugs they fix. Otherwise a
  single nouveau, single ingenic and single vmwgfx fix:

  nouveau:
   - add missing MODULE_FIRMWARE definitions

  igenic:
   - hardcode panel type DPI

  vmwgfx:
   - double free fix

  core:
   - command line mode parser fixes"

* tag 'drm-fixes-2019-09-06' of git://anongit.freedesktop.org/drm/drm:
  drm/vmwgfx: Fix double free in vmw_recv_msg()
  drm/nouveau/sec2/gp102: add missing MODULE_FIRMWAREs
  drm/selftests: modes: Add more unit tests for the cmdline parser
  drm/modes: Introduce a whitelist for the named modes
  drm/modes: Fix the command line parser to take force options into account
  drm/modes: Add a switch to differentiate free standing options
  drm/ingenic: Hardcode panel type to DPI
