Below is the list of build error/warning regressions/improvements in
v5.1[1] compared to v5.0[2].

Summarized:
- build errors: +1/-1
- build warnings: +126/-105

JFYI, when comparing v5.1[1] to v5.1-rc7[3], the summaries are:
- build errors: +0/-1
- build warnings: +102/-61

Happy fixing! ;-)

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