Subject: [PATCH v3 6/6] rpmsg: glink: Expose rpmsg name attr for glink
Date: Thu, 26 Apr 2018 15:59:05 -0700	[thread overview]
Message-ID: <1524783545-21951-7-git-send-email-clew@codeaurora.org> (raw)
In-Reply-To: <1524783545-21951-1-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>

Changes since v2:
- Remove const on attribute struct

Changes since v1:
- Add const to attribute struct
- Get name from glink channel
