[PATCH 35/51] drm/pl111: Drop explicit drm_mode_config_cleanup call

[Daniel Vetter]

It's right above the drm_dev_put().

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().

Aside: This driver gets its devm_ stuff all wrong wrt drm_device and
anything hanging off that. Not the only one unfortunately.

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

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