Thanks.  That was really fast!

I can confirm that this patch fixes the issue.

Yes, I know.  I use the M= build to do some basic load/run testing on
distro kernels.  Which is obviously a best effort thing. But it saves me
some time when it works, not needing to build and boot a more recent
kernel to just test a simple driver patch.
