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!
