[31/51] drm/ingenic: Drop explicit drm_mode_config_cleanup call

Commit Message

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

Allows us to drop the drm_driver.release callback.

This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().

v2: Explain why this cleanup is possible (Laurent).

v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)
