Hi all,
After merging the amdgpu tree, today's linux-next build (arm64 allyesconfig)
failed like this:

It's not clear to me what commit caused this, and looking at the mailing
lists it seems like this may have existed for a while and for different
configurations. I don't know if there any plans to try and fix this.
