Well this is a rather big NAK for this patch.

Only a small fraction of the firmware files amdgpu uses are actually 
optional (the ones with the *_2.bin name). All other files are mandatory 
for correct driver operation.

There is a fallback when actually no firmware files at all are found, in 
this case we at least try to get a picture on the screen so that the 
user gets a hint on what is wrong. But this path isn't tested well and 
breaks from time to time.

So when you get a message like "Direct firmware load for * failed with 
error -2" even if it's one of the "*_2.bin" files that is a clear hint 
that you should update your firmware package.

Regards,
Christian.
