Build regressions/improvements in v5.12

From: Geert Uytterhoeven
Date: Mon Apr 26 2021 - 02:42:05 EST


Below is the list of build error/warning regressions/improvements in
v5.12[1] compared to v5.11[2].

Summarized:
- build errors: +5/-0
- build warnings: +110/-10

JFYI, when comparing v5.12[1] to v5.12-rc8[3], the summaries are:
- build errors: +0/-0
- build warnings: +0/-0

Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.
