SubjectBuild regressions/improvements in v5.9-rc7
Date
Below is the list of build error/warning regressions/improvements in
v5.9-rc7[1] compared to v5.8[2].

Summarized:
- build errors: +4/-3
- build warnings: +61/-23

JFYI, when comparing v5.9-rc7[1] to v5.9-rc6[3], the summaries are:
- build errors: +5/-3
- build warnings: +15/-2

Happy fixing! ;-)

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