Date: Wed, 28 Oct 2015 14:50:43 +0100 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Paul Bolle <pebolle@...cali.nl>, Michael Ellerman <mpe@...erman.id.au>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 026/123] windfarm: decrement client count when unregistering From: Paul Bolle <pebolle@...cali.nl> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit fe2b592173ff0274e70dc44d1d28c19bb995aa7c upstream. wf_unregister_client() increments the client count when a client unregisters. That is obviously incorrect. Decrement that client count instead.
