Thanks for the update!

As the prerequisites are now in next, I can queue this in renesas-devel
for v5.11 after v5.10-rc1 has been released.
Or do you think this should be fast-tracked as a fix for v5.10 or v5.9?
I.e. is this an actual regression, or just something that never worked
before?
Note that v1 had a Fixes tag, which was lost in subsequent versions.
