Subject: [PATCH V5 4/5] rpmsg: glink: Expose rpmsg name attr for glink
Date: Fri, 22 Nov 2019 10:05:23 +0000 [thread overview]
Message-ID: <0101016e9292c7f5-f46c3ee9-55b5-4032-8b88-200ae91c8059-000000@us-west-2.amazonses.com> (raw)
In-Reply-To: <1574417087-27594-1-git-send-email-aneela@codeaurora.org>
From: Chris Lew <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.
