Subject: Build regressions/improvements in v6.2-rc2

Below is the list of build error/warning regressions/improvements in
v6.2-rc2[1] compared to v6.1[2].

Summarized:
  - build errors: +10/-13
  - build warnings: +13/-10

JFYI, when comparing v6.2-rc2[1] to v6.2-rc1[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.

when I'm talking to journalists I just say "programmer" or something like that.
