First set of IIO fixes for the 3.14 cycle.

Browse Source 
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).
