Subject: [PATCH v7 08/27] media: entity: Add has_route entity operation
Date: Mon, 24 May 2021 13:43:49 +0300 [thread overview]
Message-ID: <20210524104408.599645-9-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20210524104408.599645-1-tomi.valkeinen@ideasonboard.com>
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The optional operation can be used by entities to report whether two
pads are internally connected.
While at there, fix a Sphinx compiler warning in a comment block a few
lines above.
