Here are some more candidates that I see regularly:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/base/dd.c?id=v6.7#n590

Something like:

  git grep "\(_info(\|_warn(\).*%d"

finds a ton of them (plus a lot of unrelated hits, of course).  If you
were to do this for drivers/pci/, I would want them all for the whole
directory in a single patch, and I would take the opportunity to make
minor changes so the style is more consistent, e.g.,
"... failed (%pe)" or something.
