e21093ef6f can: janz-ican3: fix support for older hardware revisions
The Revision 1.0 Janz CMOD-IO Carrier Board does not have support for
the reset registers. To support older hardware, the code is changed to
use the hardware reset register on the Janz VMOD-ICAN3 hardware itself.

3cfc159010 at91ether: return PTR_ERR if call to clk_get fails
we are currently returning ENODEV, as the clk_get may give a exact
error code in its returned pointer, assign it to the ret by using the
PTR_ERR function, so that the subsequent goto label will jump to the
error path and clean the driver and return the error correctly.

9db273f456 net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200
One of the modes of Huawei E367 has this QMI/wwan interface:

 I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none)
 E:  Ad=83(I) Atr=03(Int.) MxPS=  64 Ivl=2ms
 E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
 E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms

Huawei use subclass and protocol to identify vendor specific
functions, so adding a new vendor rule for this combination.

The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use
the same subclass to identify the QMI/wwan function.  Replace the
existing device specific UML290 entries with generic vendor matching,
adding support for the Pantech P4200.

The ZTE MF683 has 6 vendor specific interfaces, all using
ff/ff/ff for cls/sub/prot.  Adding a match on interface #5 which
is a QMI/wwan interface.

e488921f44 bnx2x: fix rx checksum validation for IPv6
Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance
regression for IPv6. Rx checksum offload does not work. IPv6 packets
are passed to the stack with CHECKSUM_NONE.

The hardware obviously cannot perform IP checksum validation for IPv6,
because there is no checksum in the IPv6 header. This should not prevent
us from setting CHECKSUM_UNNECESSARY.

Tested on BCM57711.

8624dd2a3e net: qmi_wwan: call subdriver with control intf only
This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.

  commit 230718bd net: qmi_wwan: bind to both control and data interface

changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function.  The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.

The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended.  Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.

This was previously hidden because ixp4xx_hss includes linux/hdlc.h which
includes linux/netdevice.h which includes linux/netprio_cgroup.h which
used to include linux/module.h. The real issue was actually present since
the initial commit that added this driver since it uses macros from

John W. Linville says:

====================
Please pull these fixes intended for 3.6.  There are more commits
here than I would like -- I got a bit behind while I was stalking
Steven Rostedt in San Diego last week...  I'll slow it down after this!

There are a couple of pulls here.  One is from Johannes:

"Please pull (according to the below information) to get a few fixes.

 * a fix to properly disconnect in the driver when authentication or
   association fails
 * a fix to prevent invalid information about mesh paths being reported
   to userspace
 * a memory leak fix in an nl80211 error path"

The other comes via Gustavo:

"A few updates for the 3.6 kernel. There are two btusb patches to add
more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO()
macro and another one that add a new device id for a Sony Vaio laptop,
one fix for a user-after-free and, finally, two patches from Vinicius
to fix a issue in SMP pairing."

Along with those...

Arend van Spriel provides a fix for a use-after-free bug in brcmfmac.

Daniel Drake avoids a hang by not trying to touch the libertas hardware
duing suspend if it is already powered-down.

Felix Fietkau provides a batch of ath9k fixes that adress some
potential problems with power settings, as well as a fix to avoid a
potential interrupt storm.

Gertjan van Wingerde provides a register-width fix for rt2x00, and
a rt2x00 fix to prevent incorrectly detecting the rfkill status.
He also provides a device ID patch.

Hante Meuleman gives us three brcmfmac fixes, one that properly
initializes a command structure, one that fixes a race condition that
could lose usb requests, and one that removes some log spam.

Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some
specific devices.

Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to
using timers that aren't allocated when 2 wire bluetooth coexistence
hardware is in use.

Sergei Poselenov changes rt2800usb to do some validity checking for
received packets, avoiding crashes on an ARM Soc.

Stone Piao gives us an mwifiex fix for an incorrectly set skb length
value for a command buffer.

All of these are localized to their specific drivers, and relatively
small.  The power-related patches from Felix are bigger than I would
like, but I merged them in consideration of their isolation to ath9k
and the sensitive nature of power settings in wireless devices.

d90c92fee8 ibmveth: Fix alignment of rx queue bug
This patch fixes a bug found by Nish Aravamudan
(https://lkml.org/lkml/2012/5/15/220) where the driver is not following
the spec (it is not aligning the rx buffer on a 16-byte boundary) and the
hypervisor aborts the registration, making the device unusable.

The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461)
to replace the kmalloc+map for a single call to dma_alloc_coherent()
because that function always aligns to a 16-byte boundary.

The stable trees will run into this bug whenever the rx buffer kmalloc call
returns something not aligned on a 16-byte boundary.

a396e10019 rt2x00: Fix rfkill polling prior to interface start.
We need to program the rfkill switch GPIO pin direction to input at
device initialization time, not only when the interface is brought up.
Doing this only when the interface is brought up could lead to rfkill
detecting the switch is turned on erroneously and inability to create
the interface and bringing it up.

7f6c562dfa brcmfmac: fix get rssi by clearing getvar struct.
The function brcmf_cfg80211_get_station requests the RSSI from
the device. The complete structure used needs to be cleared
before sending the request to firmware. Otherwise the request
fails filling the logs with "Could not get rssi (-2)" messages.

2e875acd39 brcmfmac: fix race condition for rx and tx data.
On both rx and tx there is was a race condition on the queueing
of usb requests. When for example frame gets submitted it is
possible that complete function gets called even before
usb_submit_urb() returns. As a result it is possible that usb
requests get losts, which was noticed on OMAP4 pandaboard
platform. This patch fixes the race condition.

the context into account. This patch makes use of this function
instead of dev_kfree_skb().

5d9b6f2639 ath9k: Fix a crash in 2 WIRE btcoex chipsets
Generic timers for BTCOEX functionality is applicable
only for 3 WIRE BTCOEX (and MCI) chipsets.
Hence btcoex->no_stomp_timer is allocated only 3 WIRE
btcoex chipsets and in all the other cases its NULL.
Make sure we stop the generic timer only if
'btcoex->hw_timer_enabled' is true(only if its up and
running)

b3ccc1a562 ath9k_hw: enable PA linearization
This feature had been disabled in ath9k because the code to support
it was incomplete, but now the code is in sync with the internal QCA
codebase, so it's time to enable it.

On many newer devices, the calibration is assumed to be done with PA
linearization enabled.

Tests with a particular AR933x device showed that the signal emitted
at full power was highly distorted and unreliable with PA linearization
disabled. With this patch, the signal becomes clear and stability
is improved.

51dea9be7e ath9k: fix PA linearization calibration related crash
Before PAPRD training can run, the card needs to have sent a packet for
thermal calibration. Sending a dummy packet with the PAPRD training flag
set causes a crash under some circumstance.
Fix the code by replacing the dummy tx with a delay that waits for a
real packet tx to have occurred.
