Bug#969264: Warning message still present in Bullseye 11.2

I just updated my Debian amd64 system from Buster to Bullseye as per

https://www.debian.org/releases/bullseye/amd64/release-notes/ch-upgrading.en.html

I have to admit I cut some corners and enabled backports and Fast Track and did the update in one go.

All went well, short of the error discussed in this bug appearing at the boot console

[ 20.208399] iwlwifi 0000:02:00.0: firmware: failed to load iwl-debug-yoyo.bin (-2)
[ 20.208429] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware

This is problematic in three ways

1. The debug firmware is not supplied nor needed for daily usage

2. The Wiki page referenced (https://wiki.debian.org/Firmware) does not provide any pointers to useful information

3. The section about intel-microcode in Chapter 5

https://www.debian.org/releases/bullseye/amd64/release-notes/ch-information.en.html#intel-microcode

mentions possible problems with firmware-iwlwifi for Bullseye

Blacklisting the module has been suggested earlier in this bugreport, but it has not been reached my system as of yet.

Unexperienced Linux users can easily be putt off by such errormesages.

Is there a fix for this planned soon?
