ide-cd: move lba_to_msf() and msf_to_lba() to <linux/cdrom.h>
* Move lba_to_msf() and msf_to_lba() to <linux/cdrom.h> (use 'u8' type instead of 'byte' while at it). * Remove msf_to_lba() copy from drivers/cdrom/cdrom.c. Acked-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
