[Bug 30335] mmc subsystem needs MODALIAS love

[Scott James Remnant]

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
The mmc subsystem doesn't currently generate MODALIAS and the device
drivers (mmc_block, anyway) don't define aliases that map to this.

This means we don't know we have to load the secret mmc_block module to
make the newly inserted device actually work.
