Below is the list of build error/warning regressions/improvements in
v5.4-rc4[1] compared to v5.3[2].

Summarized:
- build errors: +10/-3
- build warnings: +142/-119

JFYI, when comparing v5.4-rc4[1] to v5.4-rc3[3], the summaries are:
- build errors: +0/-1
- build warnings: +93/-59

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.
