Subject: [PATCH 7/7] drm/udl: Remove struct udl_connector
Date: Thu,  4 Apr 2024 17:03:24 +0200	[thread overview]
Message-ID: <20240404150857.5520-8-tzimmermann@suse.de> (raw)
In-Reply-To: <20240404150857.5520-1-tzimmermann@suse.de>

Udl's struct udl_connector is an empty wrapper around struct
drm_connector. Remove it. Allocate the connector as part of struct
udl_device and inline the init function into its only caller.
