Firmware for Netgear R7800 has no wireless (broken ath10k wifi for QCA99xx)

I build a firmware from the latest LEDE source, but I can't start wireless and there is no Wireless in luci menu.
I have tried the lastest Development Snapshot builds, has the same issue.
But @hnyman 's build works well.

Yes, recent commit to introduce support for ipq40xx devices broke ath10k wifi for several wifi chips. The reason the removal of 936-ath10k_skip_otp_check.patch by commit https://git.lede-project.org/?p=source.git;a=commit;h=cc189c0b7fa015978b04bb663a75b1da726376b5

It is still unfixed in LEDE master, but I have included a small fix in my own build and thatswhy my own build has wifi even now.

Explanation can be found in discussion in Netgear R7800 exploration (IPQ8065, QCA9984)

Patch available in PR 995: https://github.com/lede-project/source/pull/995

OK, Thank you very much.
