From fe2b592173ff0274e70dc44d1d28c19bb995aa7c Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Fri, 31 Jul 2015 14:08:58 +0200 Subject: windfarm: decrement client count when unregistering wf_unregister_client() increments the client count when a client unregisters. That is obviously incorrect. Decrement that client count instead.
