Subject: [PATCH v2 2/8] drm/fbdev-generic: Remove unused prefer_shadow_fbdev flag
Date: Mon, 20 Mar 2023 16:07:45 +0100 [thread overview]
Message-ID: <20230320150751.20399-3-tzimmermann@suse.de> (raw)
In-Reply-To: <20230320150751.20399-1-tzimmermann@suse.de>
Remove the flag prefer_shadow_fbdev from struct drm_mode_config.
Drivers set this flag to enable shadow buffering in the generic
fbdev emulation. Such shadow buffering is now mandatory, so the
flag is unused.
