[PATCH v4 0/3] drm/udl: Replace fbdev by generic emulation

[Thomas Zimmermann <tzimmermann@suse.de>]

The udl driver can use the generic fbdev emulation. After conversion,
a number of cleanups can be applied.

The fbdev conversion is in patch 1. As udl was the only remaining
external user of unlink_framebuffer(), that function now becomes an
internal interface of the fbdev code (Patches 2 + 3).

V4 of the patchset keeps udl_gem_object_free_object(). The function
is still required to clean up after the damage handler mapped a BO.

The patchset has been tested by running the console, X11 and Weston
on a DisplayLink adapter.

v4:
	* go back to 24 bpp by default, 16 bpp for console
	* keep udl_gem_object_free_object(); required by damage handler
v3:
	* use 32 bpp by default
	* use defaults for several callback functions
	* remove all fb module parameters
	* remove udl_fbdev_init()
v2:
	* converted udl to SHMEM and recreated fbdev patchset on top

Thomas Zimmermann (3):
  drm/udl: Replace fbdev code with generic emulation
  drm/fb-helper: Remove drm_fb_helper_unlink_fbi()
  fbdev: Unexport unlink_framebuffer()
