* <linux/patchkey.h> -- definition of _PATCHKEY macro
*
* Copyright (C) 2005 Stuart Brady
*
* This exists because awe_voice.h defined its own _PATCHKEY and it wasn't
* clear whether removing this would break anything in userspace.
*
* Do not include this file directly. Please use <sys/soundcard.h> instead.
* For kernel code, use <linux/soundcard.h>
