Merge tag 'iio-fixes-for-3.14a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus

Jonathan writes:

First set of IIO fixes for the 3.14 cycle.

Included is the patch previously set as the fourth round for 3.13 which was
to late to be appropriate.

* Another endian fix (ad799x adc) due to missuse of the IIO_ST macro (which
  is going away very shortly)
* A reversed error check in ad5933 which will make the probe fail.
* A buffer overflow in the example code in the documentation.
* ad799x was freeing an irq that might or might not have been requested.
* tsl2563 was checking the wrong element of chan_spec for modifiers. Thus some
  sysfs reads would give the wrong values.
* A missing dependency on HAS_IOMEM in spear_adc and lpc32xx was causing some
  test build failures (on s390 and perhaps elsewhere).

I also have a few fixes queued up for things that went in during the 3.14
merge window which will follow as a separate pull request (to avoid rebasing
my tree).
