Thanks for the email, kernel test bot. I'm not sure my patch would be
the cause of this error, especially since my patch did not touch
bluetooth at all. Only the ham radio driver. 

I did find an email [0] from a year ago with the exact same error in
the same file.

Dan, what your thoughts?

Is this a Clang bug?

I can't imagine what's going on here.  I didn't try the reproducer, but I
I downloaded the .config and did a clang19 build and it worked for me.  I
wouldn't worry about it.

Yes, I think it is pretty obvious that the fingered change is not
responsible for the warning, it is present in mainline. It is more than
likely a Clang problem, I will do some investigating.
