[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.
