[alsa-devel] [PATCH 12/15] oxfw: Add support for Behringer/Mackie devices

[Takashi Sakamoto]

Some devices produced by Behringer/Mackie are based on OXFW970/971. This
commit adds support for them. Additionally, this commit changes the way to
name card with some information in config rom.

The devices support capture/playback of PCM-samples and some of them
supports capture/playback of MIDI messages. These functionalities are
implemented by followed commits.
