In commit cf6f7e1d ("tipc: dump monitor attributes"), I dereferenced a pointer before checking if its valid. This is reported by static check Smatch as: net/tipc/monitor.c:733 tipc_nl_add_monitor_peer() warn: variable dereferenced before check 'mon' (see line 731) In this commit, we check for a valid monitor before proceeding with any other operation.
