Re: [PATCH 0/5] staging:iio: drop sw_ring buffer implementation.

[Jonathan Cameron <jic23@kernel.org>]

Added all but patch 4 to the togreg branch of
iio.git given the only reason this was held was the just merged
series cleaning up the adis16400 driver (which included as a
side effect removing the code patch 4 dealt with).
