Subject: Build regressions/improvements in v6.0-rc4

Below is the list of build error/warning regressions/improvements in
v6.0-rc4[1] compared to v5.19[2].

Summarized:
  - build errors: +4/-15
  - build warnings: +7/-28

JFYI, when comparing v6.0-rc4[1] to v6.0-rc3[3], the summaries are:
  - build errors: +3/-16
  - build warnings: +0/-0

Happy fixing! ;-)

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