Jonathan writes:

First round of IIO fixes for the 3.10 cycle.

The usual mixed bag of little fixes.

1) A fix for mxs-lradc having missed out on some global abi changes that and
   hence being unable to start up buffered output.
2) Clean up error handling in tsl2x7x
3) A build fix for some of the dac drivers when they have spi master support
   built in, but i2c support build as a module.
4) Add a missing disable after a oneshot capture to the st sensor core.
5) Exynos adc driver took a novel an incorrect route to get at its private
   data store.
