Subject: [patch net-next] rxrpc: checking for IS_ERR() instead of NULL

From: Dan Carpenter <[email-masked]>
Date: Sat, 18 Jun 2016 11:44:03 +0300

rxrpc_lookup_peer_rcu() returns NULL on error, it never returns error
pointers.

Fixes: be6e6707f6ee ('rxrpc: Rework peer object handling to use hash table and RCU')
