Merge tag 'iio-fixes-for-3.12c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-linus
Jonathan writes:
Third set of IIO fixes for the 3.12 cycle.
Two little ones this time:
1) A missing clk_unprepare in adf4350.
2) A missing free of the active_scan_mask when iio_disable_all_buffers is
called during an unexpected device removal. This leak was introduced by
the fix
a87c82e454f184a9473f8cdfd4d304205f585f65 iio: Stop sampling when the device is removed
and hence is a regression fix.
