Hmm. I guess this check might trigger if you tried to export an SD card
slot over UMS, yet there was no SD card present. Still, patch 6/8 in
this series resolves this, since at least for MMC devices, get_device()
calls mmc_init() internally, and hence returns an error in this case.
This is more direct that checking the device size.
