I built and tested a linux-next20260330 kernel with this patch set.
The testing was on a x86/x64 VM running on Hyper-V locally on my
laptop. I also applied a follow-on update to mark as const the remaining
4 channel attributes that were presumably missed in Patch 4 of this
series (see my comments there).

Everything worked fine with no issues.
