Subject: Build regressions/improvements in v5.16-rc6

Below is the list of build error/warning regressions/improvements in
v5.16-rc6[1] compared to v5.15[2].

Summarized:
  - build errors: +6/-13
  - build warnings: +16/-29

JFYI, when comparing v5.16-rc6[1] to v5.16-rc5[3], the summaries are:
  - build errors: +1/-5
  - build warnings: +0/-0

Happy fixing! ;-)

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