For those getting build errors, this is due to the related 5.14 build
patch not being part of the Testing package (patch level 2), it was
added in patch level 3 which was in Sid/Unstable but apparently never
migrated to Testing. I've been having the same issue too.
It appears that a new Nvidia driver version is in Sid (470.63.01), so
eventually when that migrates down, it should fix this issue. Hopefully
that speeds up because systems with Nvidia graphics are unable to run
the newer 5.14 kernel at the moment, and have to stick with 5.10.
