From: Pavel Machek <pavel@...e.cz>
To: perex@...ex.cz, kernel list <linux-kernel@...r.kernel.org>,
Trivial patch monkey <trivial@...nel.org>, tiwai@...e.de
Subject: sound/usb/usbaudio.c: printk() is fine
printk() works perfectly fine, no need to obfuscate code with
snd_printk().
Signed-off-by: Pavel Machek <pavel@...e.cz>
