Subject: brcmsmac: increase timer reference count for new timers only
From: Piotr Haber <[email protected]>
commit a1fe52801a992e590cdaee2fb47a94bac9b5da90 upstream.
On hardware reintialization reference count of
already existing timers would be increased again.
This leads to problems on module unloading.
