[06/51] drm/udl: Use drmm_add_final_kfree

Commit Message

Daniel Vetter March 23, 2020, 2:49 p.m. UTC

With this we can drop the final kfree from the release function.

v2: We need drm_dev_put to unroll the driver creation (once
drm_dev_init and drmm_add_final_kfree suceeded), otherwise
the drmm_ magic doesn't happen.

v3: Actually squash in the fixup (Laurent).
