From 945eed02cd619f525e097319cd3d18c58d01da87 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 7 Nov 2008 09:08:15 +0100 Subject: ALSA: Evaluate condition in snd_BUG_ON() in non-debugging case Change snd_BUG_ON() to evaluate the given condition, at least, in syntax for avoiding compile warnings such as unused variables. The compiler should optimize out the condition evaluation in the real code, though.
