No need to quote the whole patch next time. :)
Given that MMC is sometimes used in deeply embedded environments where
udev might not be running to take care of dynamic device numbering,
I chose to stay with a static layout.
I could be convinced otherwise though. It would cause some additional
hassles for me since we start udev lateish during boot and have a
prepopulated /dev before that, but that can be dealt with.
