Subject: [PATCH 4/6] rpmsg: glink: Expose rpmsg name attr for glink
Date: Mon, 18 Dec 2017 14:02:12 -0800 [thread overview]
Message-ID: <1513634534-22861-5-git-send-email-clew@codeaurora.org> (raw)
In-Reply-To: <1513634534-22861-1-git-send-email-clew@codeaurora.org>
Expose the name field as an attr so clients listening to uevents for
rpmsg can identify the edge the events correspond to.
Signed-off-by: Chris Lew <clew@codeaurora.org>
