Build regressions/improvements in v5.2-rc1

From: Geert Uytterhoeven
Date: Mon May 20 2019 - 05:41:17 EST


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

Summarized:
- build errors: +4/-0
- build warnings: +141/-145

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.
