Below for old kernel.

I try to find driver for Geniatech DVB-T2 Stick T220 on Raspbian. http://www.geniatech.com/pa/t220.asp
On product website. It's not have driver for linux.
I found driver on this website.
Source Driver from CrazyCat https://bitbucket.org/CrazyCat/s2-liplianin-v39
I test compile and install modules.
Now It's work for me.

And I try change some code on file dw2102.c for raspberry pi kernel code for t220 driver.
Raspberry PI Kernel source https://github.com/raspberrypi/linux and recompile for test it.
Now It's work for me.
I upload source code and kernel module for this developer and product user on below link.
