I tried to find out why this driver is still there when the subsystem is gone.
According to information from https://bugzilla.kernel.org/show_bug.cgi?id=4940,
this is an alternative driver for the same hardware (the bug was about loading
both drivers simultaneously).

The proper fix should be to move the header file into drivers/scsi/dpt/ and
remove everything that this driver does not use, at least the ioctl interface,
but possibly all of the file.
