How to integrate the latest ath10k driver into an older kernel release ?

[Jean-Luc Kalmus]

Hi,
How can I integrate the latest ath10k driver into Linux kernel v3.10.20 ? 

According to this wiki https://backports.wiki.kernel.org/index.php/Documentation/integration the integration requires the backports.git and linux-next.git (or linux-next-history.git or linux-stable.git) trees to be on corresponding tags.
I found that the latest tag in the backports.git tree is ‘backports-20160324’. Therefore the latest ath10k driver I can integrate is from the kernel tag next-20160324.
I used the command: ./gentree.py --copy-list copy-list  --integrate --clean  ~/linux-next-history/ ~/linux-3.10.20/

However, when I tried to integrate drivers from the linux tag next-20170309 using a backports tree on backports-20160324, that resulted in patching errors.
How to do the integration in that case ? 

The same problem occurs when using the method explained in this wiki page https://wireless.wiki.kernel.org/en/users/drivers/ath10k/backports using the ath.git tree.
