You need to pick my patch from the patchtracker or the mailing-list
and fold into your submission as part of a series. In this way the
0-build server will build patches stacked on top of each other.
Moreover, if possible, I would suggest to split cardreader changes
from mmc host changes. In this way you would get a series along the
lines of below (not sure what order is best).
PATCH 1/3: mmc core changes.
PATCH 2/3. cardreader changes.
PATCH 3/3. mmc host changes.
Kind regards
