Subject: Build regressions/improvements in v5.1-rc4

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

Summarized:
  - build errors: +1/-1
  - build warnings: +117/-109

JFYI, when comparing v5.1-rc4[1] to v5.1-rc3[3], the summaries are:
  - build errors: +1/-0
  - build warnings: +60/-85

Happy fixing! ;-)

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

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
