The mysterious missing iwl-debug-yoyo.bin firmware

As reported a couple of days ago, I am testing kernel 5.8-rc4:

https://bkhome.org/news/202007/kernel-58-rc4-compiled.html

Running 'dmesg' reports that failed to load firmware 'iwl-debug-yoyo.bin':

iwlwifi 0000:04:00.0: Direct firmware load for iwl-debug-yoyo.bin failed with error -2

After much searching, I failed to find it, nor any explanation about what it is for, or even whether it is really needed. Well, it isn't needed, as my wifi works. Wolfram has been through the same fruitless search, and has proposed a patch to remove that failure message:

if the issue still exists when we get to the 5.8.1 kernel, and if that firmware still remains elusive, then I will probably apply that patch.
