I run it on a Qualcomm RB3 board with Qualcomm SDM845 and WCN3990.
However on that kernel I did not manage to WiFi actually work -
regardless of that patch - so I would no count it yet as fully tested.

It would be great if someone would provide some tests. I saw Steev's
replies - thanks!

Best regards,
