This initialization is not needed.

• if (err < 0)

• return err;
  

• model[31] = '\0';

The returned string is guaranteed to be zero-terminated.

• for (i = 0; i < ARRAY_SIZE(models); i++) {

• if (strncmp(models[i], model, strlen(model) == 0))
  

Why not simply strcmp()?

static int name_card(struct snd_oxfw *oxfw) { struct fw_device *fw_dev = fw_parent_device(oxfw->unit);

• char vendor[24] = {0};
• char model[32] = {0};

Same unneeded initialization.
