Below is the list of build error/warning regressions/improvements in
v5.2-rc6[1] compared to v5.1[2].

Summarized:
- build errors: +0/-0
- build warnings: +148/-117

JFYI, when comparing v5.2-rc6[1] to v5.2-rc5[3], the summaries are:
- build errors: +0/-1
- build warnings: +53/-55

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.
