This might be a silly question: I'm using "git send-email", but I
don't think there's a way to edit the e-mail before it goes out. Do I
just add "---\n[Change log]" manually in the commit description?

This includes 2 temperature sensors that are queried via PECI (i.e.
SMBus). I generated the description from the "general description"
section in the datasheet. I think the driver doesn't implement the 2
PECI sensors at this time, but the statement about the HW is still
true.

After doing a bit more searching, I found the amazing "if: then:
else:" construct that allows to express this properly and eliminates
the code duplication. I'll follow up in PATCH v6.
Thanks
