[alsa-devel] [RFC][PATCH 30/37] ALSA: firewire-motu: add a structure for model-dependent parameters.

[Takashi Sakamoto]

MOTU FireWire series doesn't tell drivers their capabilities, thus
the drivers should have model-dependent parameters and apply it to
detected models.

This commit adds a structure to represent such parameters.
