is they said there was discussion that this should
Hi Mario,
Do you know who is the author of this patch? Why he doesn't submit it?
And are there any drawbacks by calling that function?
I could SRU the patch to Ubuntu kernel(4.8/4.10), but it's a little bit
risky to submit it to upstream if I don't understand the patch well.
To setup the test en

Yes it looks like it was refactored as a result of f2f6ecabe, but
following the refactor here is where it would go in a newer kernel.

This patch seems to fix the issue on Ubuntu 4.4 kernel.
The ath10k driver structure has been changed after 4.4, so this fix can't apply
to 4.8+ kernel,
and it looks like should stay in 4.4 kernel only.
