staging:iio: remove broken support for multiple event interfaces.
We don't have a use case for these. Two drivers appeared to use them but both report all events on the first. V2: Remove now irrelevant comment. V3: Include fixup for adc/ad7280a.c Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Acked-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
