Build regressions/improvements in v5.17-rc1

From: Geert Uytterhoeven
Date: Sun Jan 23 2022 - 07:58:15 EST


Below is the list of build error/warning regressions/improvements in
v5.17-rc1[1] compared to v5.16[2].

Summarized:
- build errors: +17/-2
- build warnings: +23/-25

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.
