commit fd96e0dba19c53c2d66f2a398716bb74df8ca85e upstream.
This just makes it easier to later embed drm into udl.
[rez] Regarding the backport to v4.14.y, the only difference is due to the fact that in v4.14.y the udl_gem_mmap() function doesn't have a local 'struct udl_device' pointer so it didn't need to be converted.
