Subject: [PATCH V6 2/5] rpmsg: Guard against null endpoint ops in destroy
Date: Wed, 20 May 2020 15:09:36 +0530	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

From: Chris Lew <>

In RPMSG GLINK the chrdev device will allocate an ept as part of the
rpdev creation. This device will not register endpoint ops even though
it has an allocated ept. Protect against the case where the device is
being destroyed.
