Pull HID fixes from Jiri Kosina:

 - fix for potential 3.9 regression in handling of buttons for touchpads
   following HID mt specification; potential because reportedly there is
   no retail product on the market that would be using this feature, but
   nevertheless we'd better follow the spec.  Fix by Benjamin Tissoires.

 - support for two quirky devices added by Josh Boyer.

Marc Kleine-Budde says:

====================
here's a patch series for net for the v3.9 release cycle. Fengguang Wu found
two problems with the sja1000 drivers:

A macro in the SH architecture collides with one in the sja1000 driver. I
created a minimal patch suited for stable, only changing this particular
define. (Once net is merged back to net-next, I'll post a patch to uniformly
use a SJA1000_ prefix for the sja100 private defines.) If you prefer, I can
squash both patches together.

Fengguang further noticed that the peak pcmcia driver will not compile on archs
without ioport support. I created a patch to limit the driver to archs which
select HAS_IOPORT in Kconfig.

715230a443 tg3: fix length overflow in VPD firmware parsing
Commit 184b89044f ("tg3: Use VPD fw version
when present") introduced VPD parsing that contained a potential length
overflow.

Limit the hardware's reported firmware string length (max 255 bytes) to
stay inside the driver's firmware string length (32 bytes). On overflow,
truncate the formatted firmware string instead of potentially overwriting
portions of the tg3 struct.

ea872d7712 sch: add missing u64 in psched_ratecfg_precompute()
It seems that commit

commit 292f1c7ff6
Author: Jiri Pirko <jiri@resnulli.us>
Date:   Tue Feb 12 00:12:03 2013 +0000

    sch: make htb_rate_cfg and functions around that generic

adds little regression.

Before:

# tc qdisc add dev eth0 root handle 1: htb default ffff
# tc class add dev eth0 classid 1:ffff htb rate 5Gbit
# tc -s class show dev eth0
class htb 1:ffff root prio 0 rate 5000Mbit ceil 5000Mbit burst 625b cburst
625b
 Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
 rate 0bit 0pps backlog 0b 0p requeues 0
 lended: 0 borrowed: 0 giants: 0
 tokens: 31 ctokens: 31

After:

# tc qdisc add dev eth0 root handle 1: htb default ffff
# tc class add dev eth0 classid 1:ffff htb rate 5Gbit
# tc -s class show dev eth0
class htb 1:ffff root prio 0 rate 1544Mbit ceil 1544Mbit burst 625b cburst
625b
 Sent 5073 bytes 41 pkt (dropped 0, overlimits 0 requeues 0)
 rate 1976bit 2pps backlog 0b 0p requeues 0
 lended: 41 borrowed: 0 giants: 0
 tokens: 1802 ctokens: 1802

This probably due to lost u64 cast of rate parameter in
psched_ratecfg_precompute() (net/sched/sch_generic.c).

56771e5054 carl9170: remove fast channel change feature
Marco Fonseca reported a issue with his carl9170 device:
"I'm seeing a problem with the carl driver. If I change channels
repeatedly on the 2.4ghz band, monitoring (e.g. tcpdump) will
eventually halt.  I've seen this on various versions of the carl
driver/firmware (both from 1.9.4 to 1.9.7)"
<http://marc.info/?l=linux-wireless&m=136381302428113>

The culprit was identified as "fast channel change feature" which
according to Adrian Chadd is: "... notoriously unreliable and
really only fully debugged on some very later chips."
<http://marc.info/?l=linux-wireless&m=136416984531380>

Therefore, this patch removes the fast channel change feature.
The phy will now always have to go through a cold reset when
changing channels, but it should no longer become deaf.

fe21bb02ca mwl8k: always apply configuration even when device is idle
Fix settings not being applied when the device is idle and the firmware
gets reloaded (because of changing from STA to AP mode). This caused
the device using the wrong channel (and likely band), e.g. a 5 GHz only
card still defaulted to channel 6 in the 2.4 GHz band when left
unconfigured.

This issue was always present, but only made visible with "mwl8k: Do not
call mwl8k_cmd_set_rf_channel unconditionally" (0f4316b9), since before
that the channel was (re-)configured at the next _config call even when
it did not change from the mac80211 perspective.

devices will not be woken up by writing to host registers.
This patch enables driver to wake up device by reading FW status

Also devices with sleep cookie enabled need some more time before

55f39e6739 ath9k: trivial: change spectral relayfs buffering
The spectral data provided via relay-fs introduces a buffering
latency given by the subbuf_size. To meet the requirements for
delay-sensitive applications (like real-time spectral plotter),
reduce subbuf_size and increase n_subbufs.

Marc Kleine-Budde says:

===================
this is a pull-request for net-next/master. It consists of three
patches by Lars-Peter Clausen to clean up the mcp251x spi-can driver,
two patches from Ludovic Desroches to bring device tree support to the
at91_can driver and a patch by me to fix a sparse warning in the
blackfin driver.

a33e6112d9 phy: Elimination the forced speed reduction algorithm.
In case of fixed speed set up for a NIC (e.g. ethtool -s eth0 autoneg off speed
100 duplex full) with an ethernet cable plugged off, the mentioned algorithm
slows down a NIC speed, so further cable hook-up leads to nonoperable link state.

1b5ab0def4 net: use the frag lru_lock to protect netns_frags.nqueues update
Move the protection of netns_frags.nqueues updates under the LRU_lock,
instead of the write lock.  As they are located on the same cacheline,
and this is also needed when transitioning to use per hash bucket locking.

68399ac37e net: frag, avoid several CPUs grabbing same frag queue during LRU evictor loop
The LRU list is protected by its own lock, since commit 3ef0eb0db4
(net: frag, move LRU list maintenance outside of rwlock), and
no-longer by a read_lock.

This makes it possible, to remove the inet_frag_queue, which is about
to be "evicted", from the LRU list head.  This avoids the problem, of
several CPUs grabbing the same frag queue.

Note, cannot remove the inet_frag_lru_del() call in fq_unlink()
called by inet_frag_kill(), because inet_frag_kill() is also used in
other situations.  Thus, we use list_del_init() to allow this
double list_del to work.
