I found a lot of problems with this code as well, and the 5 patches
starting from the URL below fixed the issues for me.

They are stuck as 'NA' in patchwork, but I don't know why.

You probably need this patch as well, or ath10k will crash when you
enable the debug-mask:

It is also 'NA' in patchwork.

Thanks,
Ben
