However, a negative symptom is that the radios are disabled. I did not apply
your new mac80211 patch, so that might be a reason. "wifi detect" produces no

Please use the commits from my staging tree as-is and skip John's patches.

I made a build from Felix's commits, but no help. No trace of the radios with
kernel 4.4.
There is some difference in the kernel bootlog regarding the PCI
initialisation. The later part of "PCI: enabling device..." is missing
completely from the 4.4 bootlog.
Below is data from r222 build with kernel 4.1 and the same data from kernel
4.4 build.
I tried to collect the relevant-looking info below, but please give hints for
further debugging.
