Subject: [PATCH V5 5/5] rpmsg: glink: unregister rpmsg device during endpoint destroy
Date: Fri, 22 Nov 2019 10:05:25 +0000 [thread overview]
Message-ID: <0101016e9292d0a3-de25a223-d828-4797-8971-c68bb57937b6-000000@us-west-2.amazonses.com> (raw)
In-Reply-To: <1574417087-27594-1-git-send-email-aneela@codeaurora.org>
Rpmsg device unregister is not happening if channel close is triggered
from local side and causing re-registration of device failures.
Unregister rpmsg device for local close in endpoint destroy path.
