[PATCH V5 1/5] rpmsg: glink: Use complete_all for open states

From: Arun Kumar Neelakantam
Date: Wed May 13 2020 - 01:10:30 EST


From: Chris Lew <clew@xxxxxxxxxxxxxx>

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.
