3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Piotr Haber <pha...@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.
