From a6ed0608bd289b45a9e42e3b0f33ff55bdac9b0f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 6 Nov 2013 11:07:19 +0100 Subject: ASoC: Replace BUG() with WARN() BUG() used in the driver is just to spit the stack trace on buggy points, not really needed to stop the whole operation. For that purpose, it'd be more convenient to use WARN() instead with more error information.

Instead, Use WARN_ON(), and handle the error cases accordingly.
