Looking through the commit history, the issue seems to be related to:
672cf82122be ("devlink: disallow reload operation during device cleanup")

I've reverted this commit and Linux 4.19.85-rc2 (af1bb7db before revert) will build with the configuration I'm using [2].
I haven't looked further yet though, sorry.
