We recently got rid of having to manually call iio_buffer_register() and
iio_buffer_unregister(). This is now done by the IIO core. See
http://git.kernel.org/cgit/linux/kernel/git/jic23/iio.git/commit/?h=togreg&id=3e1b6c95b990c93f4aa3b17e9f66221e2fa44bee
I don't think we actually need these non-triggered helper functions anymore.
It basically just boils down to iio_kfifo_allocate() and
iio_device_attach_buffer().
