Subject: windfarm: decrement client count when unregistering
From: Paul Bolle <pebolle@xxxxxxxxxx>
commit fe2b592173ff0274e70dc44d1d28c19bb995aa7c upstream.
wf_unregister_client() increments the client count when a client
unregisters. That is obviously incorrect. Decrement that client count
instead.
