From d15cad5df1dac17ae33152646f599f0bdc6be48e Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 18 Aug 2008 21:40:04 +0200 Subject: [PATCH] gdrom: add dummy audio_ioctl handler Make sure audio_ioctl is always defined even if being a dummy function since the cdrom_ioctl interface assumes its existence and we don't want to BUG on null ptr on some ioctls like, e.g. CDROMREADTOCENTRY, CDROMREADTOCHDR etc. when we fix CDC_PLAY_AUDIO checking in cdrom.c.
