rpmsg: qcom_glink_native: fix error return code of qcom_glink_rx_data()

2021-05-19T08:13:02Z

[ Upstream commit 26594c6bbb60c6bc87e3762a86ceece57d164c66 ] When idr_find() returns NULL to intent, no error return code of qcom_glink_rx_data() is assigned. To fix this bug, ret is assigned with -ENOENT in this case.

rpmsg: Guard against null endpoint ops in destroy

2020-09-15T03:51:03Z

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.
