[PATCH v3 4/6] rpmsg: Guard against null endpoint ops in destroy

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
