So this series reached already v12, and we'd really like to take in
some form. Although the code is still much more complex than I
wished, it's more or less readable and understandable in some level,
so I'm fine about the sound/* part.

OTOH, this contains also the changes for drivers/acpi/scan.c and
drivers/platform/x86/serial-multi-instantiate.c, and those need Acks
from the corresponding people, but it missed Cc to them (and MLs).
Now I put them to Cc.

Rafael, Hans, Ilpo, Andy, anyone else - could you guys check it?

thanks,

Takashi
