libgl1-mesa-dri depends on libllvm12 from universe

[Brian Murray]

It's not possible to install libgl1-mesa-dri from hirsute-updates (SRU bug 1932311) on a system that does not have universe enabled because it depends on libllvm12 from universe. This was not the case with the version of libgl1-mesa-dri in the release pocket because it depended upon libllvm11.

Given that llvm12 is in main for Focal and Impish maybe it should be for Hirsute too?

[Timo Aaltonen (tjaalton)]

yes it should, promotion is fine

[Łukasz Zemczak (sil2100)]

Ok, promoting this, but I'll also make sure that the security team is aware of that. Let's ping them.

Ok, promoted both the source and the one binary package:
