Hi *,

The audio-ioctls of the SCSI CD-ROM driver are broken in 2.1.12.
Someone added copy_from_user() and copy_to_user() calls to
sr_audio_ioctl(). This is WRONG. sr_audio_ioctl() gets called from
the generic cdrom driver. The generic cdrom driver handles the
user access stuff and passes a _kernel_ pointer to sr_audio_ioctl().

Fix is simple: reverse the patch for sr_ioctl.c
