| Description | In the Linux kernel, the following vulnerability has been resolved: idpf: check error for register_netdev() on init Current init logic ignores the error code from register_netdev(), which will cause WARN_ON() on attempt to unregister it, if there was one, and there is no info for the user that the creation of the netdev failed.

On removal make sure to check VPORT_REG_NETDEV flag prior to calling unregister and free on the netdev. Add local variables for idx, vport_config and netdev for readability. |
