The amdgpu driver already provides clear messages when a required
firmware file is not found. After request_firmware() returns an error,
we will print:
"{ip_name}: Failed to load firmware {fw_name}"
When the firmware is optional, we won't print that message, and handle
the firmware load in an appropriate way (re-use _1 firmware for_2 etc.)
Note that we care about informing the user *only* if the firmware was
not found. If the firmware ends up coming from the fallback loader, but
we do receive it, then we don't really care.
This is specially important since we don't print a success message on
firmware load. So if we hit the fallback loader, the user will see a
warning followed by silence, so it could cause confusion on whether the
firmware load succeed or not.
These are my 2c in the matter.

Andres
