I wonder why these have to be warnings, I get quite a lot of them and
find them rather annoying. Or is my hardware broken or something?

No, your hardware is not broken.

I know other people are disabling this in their trees too:

Patches to change that are welcome on the list.  

It's not related to this patch which just changes from pr_warning to
dev_warn, so needs to be done in a separate patch.
