[PATCH 04/11] MMC: convert bus code to use dev_groups

[Greg Kroah-Hartman]

The dev_attrs field of struct bus_type is going away soon, dev_groups
should be used instead.  This converts the MMC bus code to use the
correct field.

Chris, I can take this through my driver-core tree if you like, just let
me know what would be the easiest for you.
