Subject: [PATCH 15/29] drm/i915/gvt: devirtualize ->set_edid and ->set_opregion
Date: Tue, 2 Nov 2021 08:05:47 +0100 [thread overview]
Message-ID: <20211102070601.155501-16-hch@lst.de> (raw)
In-Reply-To: <20211102070601.155501-1-hch@lst.de>
Just call the code to setup the opregions and EDID data directly.
