MMC: tifm_7xx1 driver detects card but does not make it mountable

[bloch@verdurin.com]

Running recent kernels the insertion of a MemoryStick into the card
reader of a Sony Vaio VGNSZ3XWP is detected but the card does not seem
to be probed for partitions and hence is not made available to
userspace.

Here is the message upon card insertion:

tifm_7xx1: ms card detected in socket 0
