Subject: [PATCH v4 08/31] media: entity: Add has_route entity operation
Date: Thu, 28 Mar 2019 21:05:45 +0100	[thread overview]
Message-ID: <20190328200608.9463-9-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20190328200608.9463-1-jacopo+renesas@jmondi.org>

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.
