Driver 'mmcblk' needs updating - please use bus_type methods

[Bastien Nocera]

It doesn't need updating, the error you're seeing is:
"DMA: Out of SW-IOMMU space for 65536 bytes at device 0000:09:00.1"

Which I reported upstream here:
http://thread.gmane.org/gmane.linux.kernel.mmc/32629
but which didn't get any answers.

You can test the work-around there though.

Cheers
