[PATCH 48/51] drm/mipi-dbi: Drop explicit drm_mode_config_cleanup call
Daniel Vetter

Fri Feb 21 21:03:16 UTC 2020
Allows us to drop the drm_driver.release callback from all
drivers, and remove the mipi_dbi_release() function.
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).
