Re: [alsa-devel] [RFC 2/2] sound: ppc: keywest: drop using attach adapter

...

• /* We assume Macs have consecutive I2C bus numbers starting at 0 */
• while (adap) {

• err = keywest_attach_adapter(adap);
  

• if (!err)
  

• 	break;
  

• i2c_put_adapter(adap);
  

• adap = i2c_get_adapter(++i);
  

• }
• return 0;

What if adap is NULL in the last while loop? Isn't it supposed to return an error?

True, we probably should have something like

return adap ? 0 : -ENODEV;

Thanks!
