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

Summarized:
  - build errors: +7/-14
  - build warnings: +30/-9

JFYI, when comparing v6.2-rc4[1] to v6.2-rc3-8-g1fe4fd6f5cad346e[3], the summaries are:
  - build errors: +1/-5
  - build warnings: +21/-3

Happy fixing! ;-)

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