Subject: Build regressions/improvements in v5.9-rc8
Date:   Mon,  5 Oct 2020 11:30:24 +0200
Message-Id: <20201005093024.16032-1-geert@linux-m68k.org>
Precedence: bulk

Below is the list of build error/warning regressions/improvements in
v5.9-rc8[1] compared to v5.8[2].

Summarized:
  - build errors: +6/-8
  - build warnings: +59/-30

JFYI, when comparing v5.9-rc8[1] to v5.9-rc7[3], the summaries are:
  - build errors: +3/-6
  - build warnings: +0/-9

Happy fixing! ;-)

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