ath: fix warning on usage of REGULATORY_CUSTOM_REG
ath wants to first apply the custom regd and only later
will it revert to not using it if an alpha2 regulatory
domain is found. Since the wireless core now enforces
usage of the REGULATORY_CUSTOM_REG strictly when
wiphy_apply_custom_regulatory() is used this makes
ath adhere to the expected behaviour but also updates
the wiphy after its done with the custom usage.

* An LLCP fix for how we were setting the default MIU on a p2p link. If
there is no explicit MIU extension announced at connection time, we

* A pn544 EEPROM config update. Some of the currently EEPROM configured

mac80211: release multiple ACs in uAPSD, fix more-data bug
When a response for PS-Poll or a uAPSD trigger frame is sent, the
more-data bit should be set according to 802.11-2012 11.2.1.5 h),
meaning that it should indicate more data on the relevant ACs
(delivery-enabled or nondelivery-enabled for uAPSD or PS-Poll.)
In, for example, the following scenario:
* 1 frame on VO queue (either in driver or in mac80211)
* at least 1 frame on VI queue (in the driver)
* both VO/VI are delivery-enabled
* uAPSD trigger frame received
The more-data flag to the driver would not be set, even though
it should be.
While fixing this, I noticed that we should really release frames
from multiple ACs where there's data buffered in the driver for
the corresponding TIDs.
To address all this, restructure the code a bit to consider all
ACs if we only release driver frames or only buffered frames.
This also addresses the more-data bug described above as now the
TIDs will all be marked as released, so the driver will have to
check the number of frames.
While at it, clarify some code and comments and remove the found
variable, replacing it with the appropriate sw/hw release check.

wl1251: fix scan behaviour while not associated
With a dissasociated card I often encoutered very long scan delays.
My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.
Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.

Bluetooth: Always wait for a connection on RFCOMM open()
This patch fixes two regressions introduced with the recent rfcomm tty
rework.
The current code uses the carrier_raised() method to wait for the
bluetooth connection when a process opens the tty.
However processes may open the port with the O_NONBLOCK flag or set the
CLOCAL termios flag: in these cases the open() syscall returns
immediately without waiting for the bluetooth connection to
complete.
This behaviour confuses userspace which expects an established bluetooth
connection.
The patch restores the old behaviour by waiting for the connection in
rfcomm_dev_activate() and removes carrier_raised() from the tty_port ops.
As a side effect the new code also fixes the case in which the rfcomm
tty device is created with the flag RFCOMM_REUSE_DLC: the old code
didn't call device_move() and ModemManager skipped the detection
probe. Now device_move() is always called inside rfcomm_dev_activate().

Bluetooth: Release RFCOMM port when the last user closes the TTY
This patch fixes a userspace regression introduced by the commit
29cd718b.
If the rfcomm device was created with the flag RFCOMM_RELEASE_ONHUP the
user space expects that the tty_port is released as soon as the last
process closes the tty.
The current code attempts to release the port in the function
rfcomm_dev_state_change(). However it won't get a reference to the
relevant tty to send a HUP: at that point the tty is already destroyed
and therefore NULL.
This patch fixes the regression by taking over the tty refcount in the
tty install method(). This way the tty_port is automatically released as
soon as the tty is destroyed.
As a consequence the check for RFCOMM_RELEASE_ONHUP flag in the hangup()
method is now redundant. Instead we have to be careful with the reference
counting in the rfcomm_release_dev() function.

cfg80211: fix wext-compat for getting retry value
While getting the retry limit, wext-compat returns the value
without updating the flag for retry->flags is 0. Also in this
case, it updates long retry flag when short and long retry
value are unequal.
So, iwconfig never showing "Retry short limit" and showing
"Retry long limit" when both values are unequal.
Updated the flags and corrected the condition properly.

Bluetooth: Default to no security with L2CAP RAW sockets
L2CAP RAW sockets can be used for things which do not involve
establishing actual connection oriented L2CAP channels. One example of
such usage is the l2ping tool. The default security level for L2CAP
sockets is LOW, which implies that for SSP based connection
authentication is still requested (although with no MITM requirement),
which is not what we want (or need) for things like l2ping. Therefore,
default to one lower level, i.e. BT_SECURITY_SDP, for L2CAP RAW sockets
in order not to trigger unwanted authentication requests.

Bluetooth: Fix NULL pointer dereference when disconnecting
When disconnecting it is possible that the l2cap_conn pointer is already
NULL when bt_6lowpan_del_conn() is entered. Looking at l2cap_conn_del
also verifies this as there's a NULL check there too. This patch adds
the missing NULL check without which the following bug may occur:
