SubjectBuild regressions/improvements in v6.2-rc5
Date
Below is the list of build error/warning regressions/improvements in
v6.2-rc5[1] compared to v6.1[2].

Summarized:
- build errors: +6/-14
- build warnings: +29/-9

JFYI, when comparing v6.2-rc5[1] to v6.2-rc4[3], the summaries are:
- build errors: +0/-1
- build warnings: +0/-1

Happy fixing! ;-)

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