Merge tag 'iio-for-3.8b' of... 

Merge tag 'iio-for-3.8b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Second round of new IIO drivers and cleanups for the 3.8 cycle.

Usual mixed bag of cleanups and minor improvements including
one reversion for a patch in the previous series.

* adt7310 and adt7410 drivers merged into one.
* Revert use devm_kcalloc in at91_adc (because it doesn't exist)
* unlocking fix for error path in the ad5449
* isl29018 suspend and resume support.
* improved pseudo floating point parsing for info_mask write
attributes (and hence into write_raw).  Reject some messed up
strings.
