[Intel-gfx] [PATCH 29/51] drm/cirrus: Drop explicit drm_mode_config_cleanup call
We can even delete the drm_driver.release hook now!
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)

But as stated in other post - using drmm_mode_config_init()
would make this more readable.
