Subject: Build regressions/improvements in v6.3-rc5

Below is the list of build error/warning regressions/improvements in
v6.3-rc5[1] compared to v6.2[2].

Summarized:
  - build errors: +6/-6
  - build warnings: +56/-68

JFYI, when comparing v6.3-rc5[1] to v6.3-rc4[3], the summaries are:
  - build errors: +0/-4
  - build warnings: +0/-0

Happy fixing! ;-)

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