Bug in cdrom_ioctl?

[Per Erik Stendahl]

Hi.

In linux-2.4.2/drivers/cdrom/cdrom.c:cdrom_ioctl() branches
CDROM_SET_OPTIONS and CDROM_CLEAR_OPTIONS both return like this:

    return cdi->options;

If cdi->options is non-zero, the ioctl() calls returns non-zero.
My ioctl(2) manpage says that a successful ioctl() should return
zero. Now I dont know which is at fault here - the cdrom.c code or
the manpage. :-) Could somebody enlighten me?
