Subject: [PATCH V5 1/5] rpmsg: glink: Use complete_all for open states
Date: Fri, 22 Nov 2019 10:05:12 +0000	[thread overview]
Message-ID: <0101016e92929ca4-d99d10e1-9b60-46d2-a0fd-9eb6bc3c7b09-000000@us-west-2.amazonses.com> (raw)
In-Reply-To: <1574417087-27594-1-git-send-email-aneela@codeaurora.org>

From: Chris Lew <clew@codeaurora.org>

The open_req and open_ack completion variables are the state variables
to represet a remote channel as open. Use complete_all so there are no
races with waiters and using completion_done.
