Empty commit logs are frowned upon. Even if the bug is simple there
should be a some kind of commit log.

Preambles and bandwidths values are considered as bit shifts
when they're are used for capabilities.

I didn't provide you a Reviewed-by tag[1] during my review, please don't
create such tags yourself. For example, in this case I didn't review the
patch in detail so I'm not comfortable giving you my Reviewed-by tag.

The general idea is that you only copy paste the tag when someone gives
you one, you don't create them on your own. I think Reported-by is only
exception but there might be others.

Sorry about the newbie mistake. Let me remove the line as you advised.
