Pull staging fixes from Greg KH: "Here are 4 tiny staging and iio driver fixes for 3.12-rc4. Nothing major, just some small fixes for reported issues" * tag 'staging-3.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: staging: comedi: ni_65xx: (bug fix) confine insn_bits to one subdevice iio:magnetometer: Bugfix magnetometer default output registers iio: Remove debugfs entries in iio_device_unregister() iio: amplifiers: ad8366: Remove regulator_put
