kernel: iio: split buffer modules into separate packages
Otherwise we would need to enable IIO_TRIGGERED_BUFFER symbol in all kernels in order to be able to use any of the IIO modules which are utilizing triggered buffer based data acquisition method. Acked-by: Stijn Tintel <stijn@linux-ipv6.be> Signed-off-by: Petr Štetiar <ynezz@true.cz>
