It's not obsoleted, as I don't think Heiner's series fixes this problem,
but it may have minor conflicts.
I suggest you rebase this patch on top of Heiner's v2 to double check,
and resend if necessary, noting in the patch (after the '---') what it
applies on top of so that the MMC maintainers don't have to figure it
out.
Thanks,
Kevin
