SubjectBuild regressions/improvements in v5.11-rc7
Date
Below is the list of build error/warning regressions/improvements in
v5.11-rc7[1] compared to v5.10[2].

Summarized:
- build errors: +0/-3
- build warnings: +31/-96

JFYI, when comparing v5.11-rc7[1] to v5.11-rc6[3], the summaries are:
- build errors: +0/-0
- build warnings: +0/-0

Happy fixing! ;-)

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

Gr{oetje,eeting}s,

Geert

--
Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
