The 'struct snd_card' has 4 members for name. They're 'driver', 'shortname', 'longname' and 'mixername'. This commit names these 4 members according to two members in model-specific structure and reduce rest of members in the structure. The reason that alias names are still used is that currently supported devices, Griffin FireWave and LaCie Firewire Speaker have too long names for model and vendor field in their config rom to be over allocated buffer for the names.
