Hi John,

Thanks for helping out testing!

This patch based upon my latest mmc tree and the next branch. I tried
to apply it for 3.15, and I think you will be able resolve the
conflict - I should be quite trivial.

Patch 1 and 2 applies on 3.15 as well. So I guess testing this on 3.15
will provide us with answers if it solves our problem.

Kind regards
