Herton Ronaldo Krzesinski Feb. 5, 2013, 10:06 p.m. -stable review patch.  If anyone has any objections, please let me know.


From: Piotr Haber <phaber@broadcom.com>

commit a1fe52801a992e590cdaee2fb47a94bac9b5da90 upstream.

On hardware reintialization reference count of
already existing timers would be increased again.
This leads to problems on module unloading.
