ALSA: firewire-digi00x: add support of asynchronous transaction for incoming MIDI messages from physical controls
Digi 00x series has two types of model; rack and console. The console
models have physical controls. The model can transmit control messages.
These control messages are transferred by asynchronous transactions to
registered address.
This commit supports the asynchronous transaction.
