Subject: firmware_class: Refer to Debian wiki page when logging missing firmware
Bug-Debian: https://bugs.debian.org/888405
Bug-Debian: https://bugs.debian.org/1053764
Forwarded: not-needed
Last-Update: 2023-11-08
If firmware loading fails due to a missing file, log a second error
message referring to our wiki page about firmware. This will explain
why some firmware is in non-free, or can't be packaged at all. Only
do this once per boot.
Do something similar in the radeon drivers, where we have an early
check to avoid failing at a point where we cannot display anything.
Update 2023-11-08:
In bug 1053764 Mario Limonciello <mario.limonciello@amd.com> states
that the patch isn't needed anymore for amdgpu, so remove that part
of the patch
