Well I guess this is maybe an argument in favour of adding the
depends since unlike that issue these are actual things one
might hit in practice. Both Aries and Midas appear to be missing
selects for the MFD part of 8994, fine as long as it gets manually
selected but will blow up if it doesn't. Will send a patch for this,
but it needed not block this patch, its a separate issue.

Thanks,
Charles
