Subject: [PATCH V1 5/6] rpmsg: glink: Remove channel decouple from rpdev release
Date: Thu, 30 Jul 2020 10:48:15 +0530 [thread overview]
Message-ID: <1596086296-28529-6-git-send-email-deesin@codeaurora.org> (raw)
In-Reply-To: <1596086296-28529-1-git-send-email-deesin@codeaurora.org>
From: Chris Lew <clew@codeaurora.org>
If a channel is being rapidly restarting and the kobj release worker
is busy, there is a chance the the rpdev_release function will run
after the channel struct itself has been released.
There should not be a need to decouple the channel from rpdev in the
rpdev release since that should only happen from the close commands.
