Andy, this is due to your changes, here's the offending code:
sname = devm_kasprintf(dev, GFP_KERNEL, "%pfwP", dev_fwnode(dev));
Now that dev_fwnode() is an inline function, the compiler is confused as
to what function to select? Maybe, I don't know, it seems odd, can you
look into it?
thanks,

Hmm... I can't reproduce on my side.
Any (additional) information about compiler, architecture, etc?

I found the original report, but I don't see how to extract the defconfig /
config it used. Can you send that file to me?

Thanks!
Can't reproduce on my Debian (x86_64):
gcc (Debian 12.2.0-3) 12.2.0

Is it GCC issue?
Any pointers where I can download the compiler you are using?
