    ALSA: firewire-digi00x: exclude Avid Adrenaline from detection · acd46a6b
    Takashi Sakamoto authored
    Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to.
    However, as long as he investigated, the design of this model is hardly
    similar to the one of Digi 00x family. It's better to exclude the model
    from modalias of ALSA firewire-digi00x driver.
    
    This commit changes device entries so that the model is excluded.
