Subject: Build regressions/improvements in v5.12-rc5

Below is the list of build error/warning regressions/improvements in
v5.12-rc5[1] compared to v5.11[2].

Summarized:
  - build errors: +5/-0
  - build warnings: +110/-8

JFYI, when comparing v5.12-rc5[1] to v5.12-rc4[3], the summaries are:
  - build errors: +0/-1
  - build warnings: +0/-0

Happy fixing! ;-)

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