Ok, either I'm confusing, or I confused myself.

In the original response I sent you two patches.
take a look: There's "patch 1: make rawpower __u16"

and the other one is:

"patch2: use max_t"

what I want to know: Which patch fixed the warning as
it looks like from your response that you have applied
both on the same time on that try:
> Removing patch patches/mutt-wfg-t420-1000-8534-5234451332105763812

I have the suspicion that "patch1" actually
doesn't do anything in this regard, but you
never know.

Regards,

BTW: I've attached just one patch (patch2 - this time)
So, you don't need to extract it from the other mail
and can just apply this one. Thanks!
