Dan Carpenter 9de4ee4054 cdrom: information leak in cdrom_ioctl_media_changed()
This cast is wrong.  "cdi->capacity" is an int and "arg" is an unsigned
long.  The way the check is written now, if one of the high 32 bits is
set then we could read outside the info->slots[] array.

This bug is pretty old and it predates git.
