staging:iio:kfifo buffer implementation A very simple use of a kfifo as an alternative for the ring_sw Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Tested-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

staging:iio: rationalization of different buffer implementation hooks. 1) move a generic helper function out of ring_sw. It applies to other buffers as well. 2) Get rid of a lot of left over function definitions. 3) Move all the access functions into static structures. 4) Introduce and use a static structure for the setup functions, preenable etc. Some driver conversions thanks to Michael Hennerich (pulled out of patches that would otherwise sit after this).
