3a491aeae8 IIO fixes for v3.6-rc1
These mostly consist of fixes from Lars-Peter Clausen that were
 the first part of a large series reworking the drivers concerned.
 Turns out these drivers had quite a wealth of minor bugs.
 
 Also here are some build warning fixes for lm3533-als and
 adjd_s111 (both new drives in this cycle).
 Final elements are a a div factor overflow and a warning
 related fix in a couple of Analog Devices drivers.
 
 All in all nothing major, but a worthwhile bunch of short
 fixes.

70e01880a9 staging:iio:ad7780: Mark channels as unsigned
The values reported by the AD7780 are unsigned with a binary offset:

	0x000000 is negative fullscale
	0x800000 is zeroscale
	0xffffff is positive fullscale

So mark the channel in the channel spec as unsigned rather than signed.

4fcbcf95b7 staging:iio:ad7192: Report offset and scale for temperature channel
The temperature channel reports values in degree Kelvin with sensitivity of 5630
codes per degree. If the chip is configured in bipolar mode there is an
additional binary offset of 0x800000 and the sensitivity is divided by two.

Currently the driver does the mapping from the raw value to degree Celsius when
doing a manual conversion. This has several disadvantages, the major one being
that it does not work for buffered mode, also by doing the division by the
sensitivity in the driver the precession of the reported value is needlessly
reduced.

Furthermore the current calculation only works in bipolar mode and the current
scale is of by a factor of 1000.

This patch modifies the driver to report correct offset and scale values in
both unipolar and bipolar mode and to report the raw temperature value
for manual conversions.

58cdff6ee7 staging:iio:ad7192: Report channel offset
In bipolar mode there is a a binary offset of 2**(N-1) (with N being the number
of bits) on the reported value. Currently this value is subtracted when doing a
manual read. While this works for manual channel readings it does not work for
buffered mode. So report the offset in the channels offset property, which will
work in both modes.

Commit 3902a37028 (staging: comedi:

inverted logic bug in comedi_device_attach() for the case where the

board name.  The result of a strcmp() is being tested incorrectly.  Fix
it.

b1f093ac68 [media] staging/media/solo6x10: use module_pci_driver macro
the driver duplicates the module_pci_driver code,
how?
	module_pci_driver is used for those drivers whose

32aecdd365 slightly reduce idiocy in drivers/staging/bcm/Misc.c
a) vfs_llseek() does *not* access userland pointers of any kind
b) neither does filp_close(), for that matter
c) ... nor filp_open()
d) vfs_read() does, but we do have a wrapper for that (kernel_read()),
so there's no need to reinvent it.
e) passing current->files to filp_close() on something that never
had been in descriptor table is pointless.

b13bc8dda8 Staging tree patches for 3.6-rc1
Here's the big staging tree merge for the 3.6-rc1 merge window.
 
 There are some patches in here outside of drivers/staging/, notibly the iio
 code (which is still stradeling the staging / not staging boundry), the pstore
 code, and the tracing code.  All of these have gotten ackes from the various
 subsystem maintainers to be included in this tree.  The pstore and tracing
 patches are related, and are coming here as they replace one of the android
 staging drivers.
 
 Otherwise, the normal staging mess.  Lots of cleanups and a few new drivers
 (some iio drivers, and the large csr wireless driver abomination.)
 
 Note, you will get a merge issue with the following files:
 	drivers/staging/comedi/drivers/s626.h
 	drivers/staging/gdm72xx/netlink_k.c
 both of which should be trivial for you to handle.

3c4cfadef6 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking changes from David S Miller:

 1) Remove the ipv4 routing cache.  Now lookups go directly into the FIB
    trie and use prebuilt routes cached there.

    No more garbage collection, no more rDOS attacks on the routing
    cache.  Instead we now get predictable and consistent performance,
    no matter what the pattern of traffic we service.

    This has been almost 2 years in the making.  Special thanks to
    Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
    have helped along the way.

    I'm sure that with a change of this magnitude there will be some
    kind of fallout, but such things ought the be simple to fix at this
    point.  Luckily I'm not European so I'll be around all of August to
    fix things :-)

    The major stages of this work here are each fronted by a forced
    merge commit whose commit message contains a top-level description
    of the motivations and implementation issues.

 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
    input.

 3) TCP SYN/ACK performance tweaks from Eric Dumazet.

 4) Add namespace support for netfilter L4 conntrack helpers, from Gao
    Feng.

 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
    Yuval Mintz.

 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.

 7) Support for connection tracker helpers in userspace, from Pablo
    Neira Ayuso.

 8) Allow userspace driven TX load balancing functions in TEAM driver,
    from Jiri Pirko.

 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
    embedded gotos.

10) TCP Small Queues, essentially minimize the amount of TCP data queued
    up in the packet scheduler layer.  Whereas the existing BQL (Byte
    Queue Limits) limits the pkt_sched --> netdevice queuing levels,
    this controls the TCP --> pkt_sched queueing levels.

    From Eric Dumazet.

11) Reduce the number of get_page/put_page ops done on SKB fragments,
    from Alexander Duyck.

12) Implement protection against blind resets in TCP (RFC 5961), from
    Eric Dumazet.

13) Support the client side of TCP Fast Open, basically the ability to
    send data in the SYN exchange, from Yuchung Cheng.

    Basically, the sender queues up data with a sendmsg() call using
    MSG_FASTOPEN, then they do the connect() which emits the queued up
    fastopen data.

14) Avoid all the problems we get into in TCP when timers or PMTU events
    hit a locked socket.  The TCP Small Queues changes added a
    tcp_release_cb() that allows us to queue work up to the
    release_sock() caller, and that's what we use here too.  From Eric
    Dumazet.

15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

d47726c521 i2c: Add SCCB support
SCCB is a serial communication bus developed by Omnivision. Its 2-wire
mode is very similar to SMBus byte data transactions, but requires the
controller to ignore the ACK bit and to insert a stop condition after
each message.

Add a device SCCB flag and a message stop flag to be passed to
controller drivers.

Only one function was being used in the file, so move it to where it was
being called and delete the rest of the file, and csr_unicode.h as it's
no longer needed as well.
