ALSA: firewire-motu: add a structure for model-dependent parameters.
MOTU FireWire series doesn't tell drivers their capabilities, thus the drivers should have and apply model-dependent parameters to detected models. This commit adds a structure to represent such parameters. Capabilities are represented by enumeration except for the number of analog line in/out. Identification name also be in the structure because the units has no registers for this purpose. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
