Is that last 'S' in the kernel source tree?
If so, I'll have to find/add it to Documentation/ioctl/ioctl-number.txt,
which I sent an update patch for about 2 weeks ago.  For 'S', it now lists:

 'S'	all	linux/cdrom.h		conflict!
 'S'	80-81	scsi/scsi_ioctl.h	conflict!
 'S'	82-FF	scsi/scsi.h		conflict!
+'S'	00-7F	sound/asequencer.h	conflict!
