SubjectBuild regressions/improvements in v5.10-rc2
Date
Below is the list of build error/warning regressions/improvements in
v5.10-rc2[1] compared to v5.9[2].

Summarized:
- build errors: +2/-7
- build warnings: +23/-23

JFYI, when comparing v5.10-rc2[1] to v5.10-rc1[3], the summaries are:
- build errors: +0/-1
- build warnings: +6/-4

Happy fixing! ;-)

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