Adding "error" and "warning" to the message logs is
duplicative to the KERN_<LEVEL> logging information.

Did you all ever look at what I posted?

smaller code, consistent prefixing, consistent with

put a space after the "%s:", __func__ so there's visual
separation between the prefixes and the content.

I agree that emitting function names isn't particularly
useful.
