Merge tag 'iio-fixes-for-4.9a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
First set of IIO fixes for the 4.9 cycle.
* atlas chemical
- Fix alignment of big endian values in a larger storage (by using the right
size storage)
* maxim thermocouple
- Fix alignment of big endian values in larger (by using the correct
sized storage).
* sca3000
- Handle unexpected mode values.
* ti-adc081
- Select IIO_TRIGGERED_BUFFER to avoid build errors
