reverted them all:

for commit in $(git log --oneline v4.9..v4.10-rc4 -- drivers/usb/dwc2 |
cut -d" " -f1); do git revert --no-edit $commit || break; done

wifi still broken.

Not really.  Usually I notice this only when trying to login quickly
after boot.  Boot, then wait a few minutes, then login usually works
fine even with kernels where wifi is broken.  So this isn't a reliable
test either.

Possibly the issue is more likely to show up on a loaded system.  Trying
"systemctl restart wpa_supplicant" after a few minutes (when boot
activity has settled) doesn't fix wifi though.

cheers,
