[PATCH] QIC-02 tape drive hookup to classes in sysfs

Here is a patch to hook up the qic02 tape device to have class
support in sysfs. I have verified it compiles. I do not have access to
the hardware to test. Could someone who does please verify?

 From the file:
 * This is a driver for the Wangtek 5150 tape drive with
 * a QIC-02 controller for ISA-PC type computers.
 * Hopefully it will work with other QIC-02 tape drives as well.
