Takashi: Messages produced by snd_printk() aren't as informative as they could be -- especially when CONFIG_SND_VERBOSE_PRINTK isn't enabled, which is the case on most systems.
The routine uses printk() rather then dev_dbg(), dev_info(), or dev_err(). As a result, the messages don't say what driver or device is involved. We just get something like: [15919.883604] cannot submit urb (err = -18) That's not much help to anybody. If you didn't know what an urb was, you wouldn't even realize that this referred to a USB device. And if you had multiple USB audio devices, you wouldn't know which one it referred to. Has there been any thought of improving snd_printk(), or even better, changing the call sites to use the dev_*() routines instead?
