I skipped those three subsystems when I sent my backlog. Comparing
what I have left with the version from the patches above I see
that about 40% of the warnings in all three are already addressed
in the meantime, leaving just

I send everything else that I have to address the warnings, and
they are slowly making their way into the tree, as of today the
remaining ones are

 drivers/char/apm-emulation.c              | 5 ++---

 drivers/tty/serial/amba-pl011.c           | 6 +++---
 drivers/tty/serial/ma35d1_serial.c        | 2 +-

and I'm optimistic about most of them making it into the
next merge window. Once few enough are left, I can send
it again as a series that turns on the warning by default
and hopefully by that time we can wear down Mark enough
that he takes the patches even if he still disagrees ;-)
