dmesg kernel oops dw2102 tevii s650 usb box

Hi,

with my Tevii s650 usb box i get kernel oops in Kernel 4.13.10 and 4.13.9. I could verify that Hardware is working with older Kernels.

Thanks in advance

Patch for Tevii 650

Hi, 

I got the Tevii S650 working again!

It seems function dw2102_disconnect() in dw2102.c is called while the priv member of the dw2102_state is not intialized. 

This causes a NULL pointer deference.

The attached patch solves it.
