I think Mark was just trying to help with your observation that the
changes are messy.  I don't see any compelling reasons to avoid adding
these to mmc_host -- does anyone else feel strongly?

So, I'd say go ahead and post an updated patch that uses mmc_host,
and we can see if Mark has any thoughts.

Thanks,
