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. -Olof
