I thought so, but for some reason my tools couldn't find that.  Ah, it
was one of those "cherry picked from" drm nonsense patches.  Ugh, what a
mess, I don't know why my tools didn't notice this, normally it does for
the intel patches that show up in the tree like this.

Maybe something is busted on my end with the 6.19->7.0-rc1 transition
that my tools couldn't handle.  I thought I found all the corner cases
of that, but as it only happens every few years, odds are I missed
something somewhere...

Anyway, I'll go queue these two up for just 6.18, thanks.
