402-ath_regd_optional.patch no longer compatible with kernel since 4.7 about openwrt-old

[abhijit-mahajani-imgtec]

Hello @lockheed , can you please expand more on the issue ? how do you reproduce it? which version you are using? because currently MIPS pistachio is supporting linux 4.4.7 which is there on default branch.
Are you building for Ci40 using https://github.com/CreatorDev/openwrt build instructions or trying a new kernel with it?

The issue can be reproduced simply by trying to patch any kernel above 4.6 branch (4.8 is also affected just as 4.7 is).
I am using this patch to patch a x64 kernel on regular server/desktop linux, not OpenWRT.

I understand your focus here is OpenWRT and 4.7+ kernels are not in it yet, but since the patch was compatible with general linux kernel before, perhaps you could update it for newer kernels, or at least give me some pointers on how can I modify the patch myself?
