Subject: [PATCH 07/10] drm/fbdev-generic: Minimize hotplug error handling
Date: Mon, 23 Jan 2023 11:05:56 +0100	[thread overview]
Message-ID: <20230123100559.12351-8-tzimmermann@suse.de> (raw)
In-Reply-To: <20230123100559.12351-1-tzimmermann@suse.de>

Call drm_fb_helper_init() in the generic-fbdev hotplug helper
to revert the effects of drm_fb_helper_init(). No full cleanup
is required.
