Please don't start the commit message in the middle of a sentence.
It looks like this for some of us:

https://marc.info/?l=linux-driver-devel&m=158282701430176&w=2

I generally read the subject or the full commit message but seldom
both.

Otherwise the patch looks very good.

Could you please clarify what do you mean by the "middle of a sentence"?
The commit's message doesn't sound "middle" to me at all.

This link points to this patch, I don't quite understand what you're
trying to convey here.

The commit's title describes the change briefly, while the message gives
a rational for the change. Usually reviewer should consult the code
changes themselves for more details.

Do you have some kind of a email filter that shows only the commit's
message? Otherwise I'm not sure what's the problem.

Thanks

The commit message just says "This helps to make code cleaner a tad."
but it doesn't mention devm_platform_ioremap_resource_byname().  That
information is there in the subject but not in the commit message itself.
Take a look at the link I sent you and try to find the subject.  It's
far away from the commit message.
