Subject: [PATCH v3 11/14] media: v4l2-core: v4l2-async: Check sd->fwnode->secondary in match_fwnode()
Date: Thu, 24 Dec 2020 01:09:04 +0000 [thread overview]
Message-ID: <20201224010907.263125-12-djrscally@gmail.com> (raw)
In-Reply-To: <20201224010907.263125-1-djrscally@gmail.com>
Where the fwnode graph is comprised of software_nodes, these will be
assigned as the secondary to dev->fwnode. Check the v4l2_subdev's fwnode
for a secondary and attempt to match against it during match_fwnode() to
accommodate that possibility.
