From: Borislav Petkov Date: Mon, 18 Aug 2008 19:40:03 +0000 (+0200) Subject: viocd: add dummy audio ioctl handler X-Git-Tag: v2.6.27-rc4~41^2~7 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e636f78e5bbe95831e4d0071ee8f40b507e1cbd;p=linux-2.6 viocd: 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.
