Bug#966218: firmware: failed to load iwl-debug-yoyo.bin (-2)

[starchaser <starchaser8@gmail.com>]

I have the same problem: "firmware: failed to load iwl-debug-yoyo.bin
(-2)" in the log.
I am using Debian linux-image-5.9.0-5-amd64-unsigned (= 5.9.15-1).

I am no expert but i don't think this log message is pressent in Linux
mainline, only in Debian.
The upstream patch [0] that Jeremy mentions is not for this message
but for the upstream debug message:
"Direct firmware load for iwl-debug-yoyo.bin failed with error -2"
This message is now not shown anymore.
The message that this bug report handles is "firmware: failed to load
iwl-debug-yoyo.bin (-2)"
This message is not in upstream Linux but instead comes from an
ancient Debian kernel patch from 2012 that is still applied on
debian kernel 5.10.4-1.(firmware_class-log-every-success-and-failure.patch [1])
While the mainstream Linux logging evolved a lot since 2012 i doubt
that this patch which duplicates error logging is still wise to use.
