Chris, the partitions are always present and are a feature of the card.
I ptofusely apologize for the dev_idx issue, I should have caught that
immediately. A dev_idx is till assigned even though the name doesn't
reflect the actual assigned dev_idx for hardware partitions. That
effectively means you need to track a name_idx per main mmc_blk_data
that is only used to form the naming for the device.
I will send a patch in about 30 mins...
