1d240d3702 brcmsmac: don't leak kernel memory via printk()
Debug code prints the fifo name via custom dev_warn() wrappers. The
fifo_names array is only non-zero when debugging is manually enabled,
which is all well and good. However, it's *not* good that this array
uses zero-length arrays in the non-debug case, and so it doesn't
actually have any memory allocated to it. This means that as far as we
know, fifo_names[i] actually points to garbage memory.

I've seen this in my log:

[ 4601.205511] brcmsmac bcma0:1: wl0: brcms_c_d11hdrs_mac80211: �GeL txop exceeded phylen 137/256 dur 1602/1504

So let's give this array space enough to fill it with a NULL byte.

03d6c3b0fa iwlwifi: pcie: re-ACK all interrupts after device reset
When we reset the device, the CSR_INT gets cleared as well
as CSR_INT_MASK. Meaning that we shouldn't get any interrupt
but, due to a hardware bug, recent devices will keep sending
interrupts. This leads to an interrupt storm while stopping
the device.
The way to fix this is to ACK all the interrupts after the
device is reset so that the value of CSR_INT will stay
0xffffffff.

This reverts commit d32394fae9.

It has been reported to cause problems, Jeremiah writes:
	On an Acer C720 laptop if a suspend is performed the screen
	freezes, the machine locks up, and according to the indicator
	lights it does not enter suspend.  A hard reset is required to
	get it running again.

fc99dd0829 mwifiex: do not process broadcast mac address for del_sta
Generally broadcast mac address deauth is followed by stop_ap or start_ap.
In both cases, FW already has provision to send deauth; so there is no
need to handle broadcast mac deauthentication.

c11fb9857f mwifiex: guard station nodes access by station list lock
Station node entries should be guarded for whole of their reference
instead of just while getting node entry from station list.
It may happen that station node is retrieved may be deleted by
deauthentication event while it is still in use.

9817fffbf0 mwifiex: delete peer station's RA list upon deauthentication
This patch adds support to delete peer station's RA lists
upon station deautheticate event on AP interface. Patch also
decrements TX pending count upon removing packets from RA list.

dda9ddeb26 mwifiex: do not delete station entries in del_sta handler
A crash was observed while cfg80211 del_station handler is
called while stopping AP. This was happening because we were
deleting station list and Rx reorder table entries in del_sta
handler. While station entry is being deleted here, it may happen
that station deauth event from FW would also try to delete station
entry.

This patch fixes this crash by not deleting station entries in del_station
handler. Entry would be deleted while processing station deauth event; which
is triggered by del_station command to FW.

This patch adds support for multiple BSS interfaces (AP). In
total three AP configurations can be created. In order to use
multiple BSS firmware needs to support it.
