Subject: [PATCH v2 06/10] drm/ast: Add cursor-plane data structure
Date: Tue,  9 Feb 2021 14:46:28 +0100	[thread overview]
Message-ID: <20210209134632.12157-7-tzimmermann@suse.de> (raw)
In-Reply-To: <20210209134632.12157-1-tzimmermann@suse.de>

Cursor state is currently located throughout struct ast_private. Having
struct ast_cursor_plane as dedicated data structure for cursors helps to
organize the modesetting code.
