Merge tag 'iio-fixes-for-3.9a' of... 

Merge tag 'iio-fixes-for-3.9a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus

Jonathan writes:

"First round of iio fixes post the 3.9 merge window.

1) Some little fixes for the ad5064 dac driver.
2) A build warning 'fix' for a false positive in st_sensors
3) A couple of missing dependencies on IIO_BUFFER.

So nothing major and these mostly showed the advantages of the randconfig
builds various people have performed."
