From 656a22a105c8135a515daae3d79ede7b472c18ec Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 5 Nov 2013 18:40:01 +0100 Subject: [PATCH] ASoC: mid-x86: Use WARN_ON() instead of BUG_ON() BUG_ON() is rather useless for debugging as it leads to panic(). Use WARN_ON() and handle the error cases accordingly.
