Subject: [PATCH v3 3/6] rpmsg: glink: Use complete_all for open states
Date: Thu, 26 Apr 2018 15:59:02 -0700	[thread overview]
Message-ID: <1524783545-21951-4-git-send-email-clew@codeaurora.org> (raw)
In-Reply-To: <1524783545-21951-1-git-send-email-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.
