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).
