From: Paul Bolle <pebolle@tiscali.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.
Fixes: 75722d3992f5 ("[PATCH] ppc64: Thermal control for SMU based machines")
