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
