Thank you, this is much more useful feedback, specifically due to the
suggested patch below. I did intend to learn about the other modes and
progressively upgrade secs_to_jiffies.cocci with them in the future once
the existing instances were resolved, to help with future code
submissions. The patch below will be super helpful in that.

As it stands, I'll fix up the current rules in v2 following your
suggestion to keep the multiplication in each line to allow Coccinelle
to use the commutativity properties and find more instances.

I'll refrain from implementing the report mode until current instances
have been fixed because of the issue we have already seen[1] with CI
builds being broken. I would not want to break a strict CI build that is
looking for coccicheck REPORT to return 0 results.
