compat_ioctl: move cdrom commands into cdrom.c
There is no need for the special cases for the cdrom ioctls any more now, so make sure that each cdrom driver has a .compat_ioctl() callback and calls cdrom_compat_ioctl() directly there. Reviewed-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
