From 0f17014b340b98465fcf0de4c0d6c84a002ec53b Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Fri, 26 Mar 2010 16:07:25 +0200 Subject: [PATCH] ALSA: pcm_lib - fix xrun functionality The commit 4d96eb255c53ab5e39b37fd4d484ea3dc39ab456 broke the interrupt time xrun functionality (stream stop etc.) if the CONFIG_SND_PCM_XRUN_DEBUG is not set. This is because the xrun() is null defined without it. Fix this by letting the function xrun() to be always defined as it was before.
