SubjectBuild regressions/improvements in v5.13+
Date
Below is the list of build error/warning regressions/improvements in
v5.13+ (v5.13 + 1 commit)[1] compared to v5.12[2].

Summarized:
- build errors: +0/-6
- build warnings: +47/-29

JFYI, when comparing v5.13+[1] to v5.13-rc7[3], the summaries are:
- build errors: +0/-0
- build warnings: +0/-0

Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.

Happy fixing! ;-)

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