brcmsmac: increase timer reference count for new timers only

2013-02-04T00:24:41+00:00

commit a1fe52801a992e590cdaee2fb47a94bac9b5da90 upstream.

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

brcmfmac: fix a double spin_unlock_irqrestore issue in dpc

2012-05-02T18:02:03+00:00

dpc_tl_lock is not acquired in the error handle code for bus down.
But it's unlocked using spin_unlock_irqrestore after finishing task
list walk down. Grab the lock before breaking the loop to avoid a
double unlock.

brcm80211: fmac: fix missing completion events issue

2012-04-27T19:20:39+00:00

dpc takes care of all data packets transmissions for sdio function
2. It is possible that it misses some completion events when the
traffic is heavy or it's running on a slow cpu. A linked list is
introduced to make sure dpc is invoked whenever needed.

brcm80211: fmac: fix SDIO function 0 register r/w issue

2012-04-27T19:20:39+00:00

SDIO stack doesn't have a structure for function 0. The structure
pointer stored in card->sdio_func[0] is actually for function 1.
With current implementation the register read/write is applied to
function 1. This pathch fixes the issue.

brcmsmac: "INTERMEDIATE but not AMPDU" only when tracing

From the code comment I understand that this something that can -
and does, quite frequently - happen.

brcm80211: smac: resume transmit fifo upon receiving frames

2012-04-13T18:05:35+00:00

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.
