nvidia-340xx package fails to compile

[Hans <hans.ullrich@loop.de>]

Hi folks, 

those who like just hassle hours and hours with nvidia-340xx-kernel builds, 
please note, that the version 340.108-3 does NOT build on kernel-version 
5.10.0-6-amd64. No chance!

Also the official NVidia-*.run does NOT build!

However, I downloaded manually all (still not official in the testing repo 
database) nvidia-packages from the repo with the version 

340.108-10-*bpo*

and Volila, they build like a charme and working without any problems.

Maybe they should be released as fast as possible?

Hope this helps.

Best regards and thanks for the great work!

Hans
