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.
