commit a1fe52801a992e590cdaee2fb47a94bac9b5da90 upstream. On hardware reintialization reference count of already existing timers would be increased again. This leads to problems on module unloading.

commit 5e379203c7788b7af01150bfadbc74d2797a2ef4 upstream.
The A-MPDU code checked against a retry limit, but it was using
the wrong variable to do so. This patch fixes this to assure
proper retry mechanism.
This problem had a side-effect causing the mac80211 flush callback
to remain waiting forever as well. That side effect has been fixed
by commit by Stanislaw Gruszka:

[Not needed upstream --- this bug is specific to 3.2.y.]
Commit c6c44893c864, which removes the flag argument from brcms_b_mute,
is not part of 3.2.y, and we forgot to adjust a new call accordingly
when applying commit badc4f07622f ("brcm80211: smac: resume transmit
fifo upon receiving frames").
drivers/net/wireless/brcm80211/brcmsmac/main.c: In function 'brcms_c_recvctl':
drivers/net/wireless/brcm80211/brcmsmac/main.c:7882:4: error: too few arguments to function 'brcms_b_mute'
drivers/net/wireless/brcm80211/brcmsmac/main.c:2538:13: note: declared here
Earlier build tests missed this because they didn't include this driver
due to 'depends on BCMA=n'.

commit badc4f07622f0f7093a201638f45e85765f1b5e4 upstream. There have been reports about not being able to use access-points on channel 12 and 13 or having connectivity issues when these channels were part of the selected regulatory domain. Upon switching to these channels the brcmsmac driver suspends the transmit dma fifos. This patch resumes them upon handing over the first received beacon to mac80211. This patch is to be applied to the stable tree for kernel versions 3.2 and 3.3.

commit f96b08a7e6f69c0f0a576554df3df5b1b519c479 upstream. This patch workaround live deadlock problem caused by infinite loop in brcms_c_wait_for_tx_completion(). I do not consider the patch as the proper fix, which should fix the real reason of tx queue flush failure, but patch helps with system lockup.
