[PATCH 3.12 026/123] windfarm: decrement client count when unregistering

Show all headers | View raw

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")
