Thanks, for the answers. 

I already tried before writing my message to compile my custom ath10k backports. However when I was following your guide I was not able to create the backports output tree. The gentree.py script was giving me a dependency problem :

You need to have installed: spatch >= 1.0.0-rc24
Try installing the package: coccinelle

So, I did installed the latest coccinelle version but the dependency was still there. After one day struggling I found that its a bug and can be solved with this patch :

I still have a question regarding backports, and kernel releases. I am quite new in all this world so that's why I was a little bit confused.  Correct me if I am wrong. Backports are used to install the newest (or whatever version ) of drivers in the current kernel you have, right ? So you get the same result than compiling the entire kernel with your modified driver ?
