From 60ed286a61b43e3fedf18e63f2d71b758f3505aa Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 18 May 2011 11:28:39 +0200 Subject: ALSA: usb-audio: make hwc_debug a noop in case HW_CONST_DEBUG is not set Just defining it to nothing is dangerous as it can alter the code execution flow, for example when used in as only function in a conditional code block.
