IMO, the fact that the comment is under a bunch of filenames, should be
pretty obvious that there are more devices, especially since this entire
patchset is fixing same kind of problem for all of these boards.
Anyway, will be more explicit next time.

As for v2, it doesn't warrant one, but I was telling reviewers that I
realized that there are more than just these devices that need this fixed,
basically promising to fix all and include them in v2, if a respin is
necessary. Which it might, if you merge Alex's EC XPS13 patchset first.

Thanks for reviewing!
