[Geert Uytterhoeven <geert@linux-m68k.org>]

Below is the list of build error/warning regressions/improvements in
v5.18-rc4[1] compared to v5.17[2].

Summarized:
  - build errors: +28/-5
  - build warnings: +19/-16

JFYI, when comparing v5.18-rc4[1] to v5.18-rc3[3], the summaries are:
  - build errors: +6/-7
  - build warnings: +14/-1

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.
