Merge tag 'iio-for-v3.7b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23...

Second set of IIO rework and new drivers for the 3.7 cycle.

Firstly we have the second half of a series reworking support for
the various sigma delta ADCs from Analog.  The first half was fixes
that have already merged in the v3.6 cycle.  Other than some
little cleanups this mainly consists of a unifying library module
that the various drivers can then use.  Another new driver is
using this undergoing revisions and the code reduction already
seen from this is considerable.  A nice piece of work.

Secondly we have a good number of tidying up patches from various
sources doing things like adding include guards and removing
unintended header ordering requirements.  Also a mass annotation
of missing __devinit/exit.  Peter Meerwald has been getting around
with cleanup of lis3l02dq, documentation fixes, white space clenaups
and a small issue with my spelling ;)

Thirdly we have some improvements to our kfifo usage that have
been around for a while but are now suddenly in demand from a
number of users.

Forth we have some clk_prepare_enable and clk_prepare_disable
cleanups.

Fifth is the addition of i2c dacs to the ad5446 driver

Finally we have some email address updates. I'll do the
MAINTAINERS one separately.

So a general mixed bag but nothing terribly controversial
or 'exciting'.
