Subject: Build regressions/improvements in v5.10

Below is the list of build error/warning regressions/improvements in
v5.10[1] compared to v5.9[2].

Summarized:
  - build errors: +2/-7
  - build warnings: +21/-30

JFYI, when comparing v5.10[1] to v5.10-rc7[3], the summaries are:
  - build errors: +0/-0
  - build warnings: +2/-6

Happy fixing! ;-)

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