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).
The patchset has been tested by running the console, X11 and Weston on a DisplayLink adapter.
v5: * initialize console after registering device 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
