Subject[PATCH 37/93] brcmsmac: increase timer reference count for new timers only
Date
3.5.7.5 -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.
