[PATCH v3] ALSA: aoa: convert bus code to use dev_groups

[Quentin Lambert <lambert.quentin@gmail.com>]

The dev_attrs field of struct bus_type is going away, sue dev_groups instead.
This converts the soundbus code to use the correct field.

These modifications were made using Coccinelle.

  - Revert to the version of the patch where the files weren't merge.

    Takashi.
