Yes, I'm supposed to be maintaining clkdev, but I'm busy with other
stuff (such as reorganising my network, helping people with SFP issues,
I'm supposed to be replying to Arend over a brcmfmac issue that has been
on-going since Christmas which I haven't yet been able to doing the next
test...)

It's there because it's part of the mainline kernel and has been
since v5.0-rc1.  So, if you depend on that commit, basing off
v5.0-rc1 is probably sane, unless there's something else that
conflicts.
