6bc61f4d8e libertas: improve function init/shutdown handling for SD8688
This patch is to incorporate Dan Williams' comments for commit:
"libertas: implement function init/shutdown commands for SD8688"

1. remove fn_init_required and fn_shutdown_required variables from
lbs_private structure. If required, __lbs_cmd() will be called
directly to send function init/shutdown command for SD8688 in
if_sdio_probe() or if_sdio_remove() callback.

2. add global variable "user_rmmod" to distinguish between the module
removal case and the card removal case. This flag will be checked in
if_sdio_remove() against SD8688 card to determine whether or not the
function shutdown command needs to be sent.

3. remove "card" from if_sdio_model structure as it cannot store
card pointers for multiple cards. Besides, it's no longer needed
to store the "card" pointer with changes #1 & #2 above.

6d7db193f2 ar9170: cancel led worker properly on exit
"[PATCH 3/4 v2] ar9170: fix LED power state handling" revealed
a bug which can cause a ugly crash.

The delayed worker is canceled before the LED class functions are
unregistered... So, if something manages to update the LEDs
while unregister routine is running the timer could fire _after_ the
module has been unloaded.

66d008139c ar9170usb: more minor fixes
This patch contains a few more mostly random fixes for the USB front-end.

1. handle irq command response, instead of printing it to the console.

2. remove fixed FIXME.
    (real fix: "ar9170usb: reset device on resume". )

3. some more one-liner.
	- get rid of a useless "return;"
	- add a few branch prediction hints in hot-paths
	etc.

729e9c7663 cfg80211: fix for duplicate userspace replies
This fixes an incorrect assumption (BUG_ON) made in
cfg80211 when handling country IE regulatory requests.
The assumption was that we won't try to call_crda()
twice for the same event and therefore we will not
recieve two replies through nl80211 for the regulatory
request. As it turns out it is true we don't call_crda()
twice for the same event, however, kobject_uevent_env()
*might* send the udev event twice and/or userspace can
simply process the udev event twice. We remove the BUG_ON()
and simply ignore the duplicate request.

For details refer to this thread:

546256fbd0 ath9k: Add sanity check for beacon_int in adhoc/mesh case
It looks like mac80211 can request the driver to start beaconing with
a beacon interval of zero in some cases (at least for mesh point). This
does not sound correct and something may need to be fixed in
mac80211. However, taken into account the unpleasantness of getting
stuck in an infinite busy loop with rtnl_lock held, let's add a quick
workaround in the driver to avoid the worst symptom while someone more
familiar with the mesh implementation can figure out what should be done
with mac80211 as far as beacon interval configuration is concerned.

2493928e4d ath9k: Add "debug" file to debugfs
This patch adds the debug file to the ath9k debugfs, which lets you modify
the debug_mask at runtime, without having to reload the ath9k module.

bedf087af9 ath9k: Combine legacy and 11n rc statistics
This patch combines the legacy and 11n rcstats into one, using the normal
rate table indices instead of two separate indices for each mode.  Legacy
rates also get all of the PER and retry information, now, too.

b74444f8a9 ath9k: Reset SC_OP_TSF_RESET flag after stuck beacon
I have a TrendNet 652-BRP running OpenWRT + ath9k very well.  The only
problem is that the beacon gets stuck maybe once a day.  After
Vasanthakumar Thiagarajan's "ath9k: cleanup beacon parameters
configuration" patch, ath9k would nearly re-configure the beacons after it
detected the stuck beacon, and did a reset.  But it would fail the
SC_OP_TSF_RESET check in ath_beacon_config_ap.  This patch gets the beacon
fully reconfigured after the reset.

034d655ee7 cfg80211: disallow interfering with stations on non-AP (part 2)
On non-AP interfaces userspace has no business interfering with
the station management, this can confuse mac80211 (and other
drivers probably wouldn't support it anyway). Allow adding and
removing stations only on AP interfaces.

(Reconcile this w/ previous version of patch posted with same
subject... -- JWL)

d651ae3278 iwlwifi: avoid build warning in iwl-core.
When building when CONFIG_IWLWIFI_DEBUG is not set, we get the following
warning:
/work/src/w/drivers/net/wireless/iwlwifi/iwl-core.c: In function ‘iwl_isr’:
/work/src/w/drivers/net/wireless/iwlwifi/iwl-core.c:1707: warning:
unused variable ‘inta_fh’

This patch avoids this warning by adding #ifdef CONFIG_IWLWIFI_DEBUG
before the declaration of inta_fh in iwl_isr() in
drivers/net/wireless/iwlwifi/iwl-core.c

51b50fbeb5 cfg80211: validate AID of stations being added
We have some validation code in mac80211 but said code will
force an invalid AID to 0 which isn't a valid AID either;
instead require a valid AID (1-2007) to be passed in from
userspace in cfg80211 already. Also move the code before
the race comment since it can only be executed during STA
addition and thus is not racy.

f488b72de5 net/libertas: make SPI interface big endian aware
The comment (which I remove) says that the translation is done SPI routines.
IMHO this can't work because the SPI driver does not know whether the incomming
bytes are part of the registers/bytes which need to be flipped or part of
packet data which has to remain untouched.
While adding le helpers I also removed spu_write_u32() which has no users.

fbcc0e2ce5 fsl_pq_mido: Set the first UCC as the mii management interface master
Current code makes the UCC whose register range includes the current mdio
register to be the MII managemnt interface master of the QE. If there is more
than one mdio bus for QE, the UCC of the last mdio bus will be the MII
management interface master which will make the primary mdio bus working
unproperly, e.g. can not get the right clock. Normally the primary mdio bus is
the first UEC's mdio bus.
This patch allows the first UCC to be the MII management interface master of the
multiple UCC mdio buses.
