Udl's damage-handling code requires clean up before switching the driver
to simple-pipe helpers. Patches 1, 2 and 7 remove unused state variables
and statistics. Patches 3 to 5 reorganizes the damage handler to be more
readable. Patch 6 moves dma-buf begin/end calls into the damage handler,
so it will run during page-flip andmodeset operations.

The patchset has been tested by running fbdev console emulation, X11, and
Weston with a DisplayLink adapter.

Thomas Zimmermann (7):
  drm/udl: Remove unused statistics counters
  drm/udl: Don't track number of identical and sent pixels per line
  drm/udl: Vmap framebuffer after all tests succeeded in damage handling
  drm/udl: Move clip-rectangle code out of udl_handle_damage()
  drm/udl: Move log-cpp code out of udl_damage_handler()
  drm/udl: Begin/end access to imported buffers in damage-handler
  drm/udl: Remove field lost_pixels from struct udl_device
