Date: Mon Jan 04 2021 - 04:58:00 EST


Below is the list of build error/warning regressions/improvements in
v5.11-rc2[1] compared to v5.10[2].

Summarized:
- build errors: +3/-3
- build warnings: +23/-95

JFYI, when comparing v5.11-rc2[1] to v5.11-rc1[3], the summaries are:
- build errors: +2/-0
- build warnings: +51/-0

Happy fixing! ;-)

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