The only driver exporting filter_type_available attribute is ad7779 and it only supports sinc3 and sinc5 filters. Remove options that are not presented through filter_type_available attribute. Signed-off-by: Marcelo Schmitt <marcelo.schmitt@xxxxxxxxxx> --- Maybe this is not worth it (or desirable?) since the options may come back in the future if new drivers happen to need them.
