Subject: [PATCH drm-misc-next v3 7/7] drm/arm/hdlcd: remove calls to drm_mode_config_cleanup()
Date:   Sat,  1 Oct 2022 03:19:05 +0200
Message-Id: <20221001011905.433408-8-dakr@redhat.com>
In-Reply-To: <20221001011905.433408-1-dakr@redhat.com>

drm_mode_config_init() simply calls drmm_mode_config_init(), hence
cleanup is automatically handled through registering
drm_mode_config_cleanup() with drmm_add_action_or_reset().

While at it, get rid of the deprecated drm_mode_config_init() and
replace it with drmm_mode_config_init() directly.
