Below is the list of build error/warning regressions/improvements in
v5.3-rc4[1] compared to v5.2[2].

Summarized:
- build errors: +5/-1
- build warnings: +137/-136

JFYI, when comparing v5.3-rc4[1] to v5.3-rc3[3], the summaries are:
- build errors: +0/-4
- build warnings: +105/-69

Happy fixing! ;-)

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