 Thanks to Randy for the report. Sorry for the slow response.
 I've been meaning to carefully check for any remaining cases like
 this.
 Here I've kept the selection of IIO_SW_RING separate from
 IIO_TRIGGER as it will go away fairly shortly when the ring buffer
 type becomes configurable on a per device basis, whereas the
 IIO_TRIGGER select will remain. Whether to retain the option to
 remove the support for ring buffers entirely is one for after that
 support is in place.

 Touch wood I think this is the last one, but I'll try a selection of
 unusual combinations now and post others as replies to this email.
