Ok, next lessons :)

Before you send a patch, do:

$ git diff | ./scripts/get_maintainer.pl

or if you've committed it already:

$ git log -p -1 | ./scripts/get_maintainer.pl

to know who to Cc.

I've added the respective mailing lists to Cc because this is a trivial
addition of PCI IDs and generally maintainers want to see it as an FYI
thing, thus Ccing the mailing list only. But you can just as well Cc the
maintainers too - they can manage the mail volume. :)

And last but *definitely* not least, the most important lesson: *always*
- I can't stress this enough - *always* build *and* test your patch
before sending:

drivers/edac/amd64_edac.c:2326:19: error: ‘f17_base_addr_to_cs_size’ undeclared here (not in a function); did you mean ‘f17_addr_mask_to_cs_size’?
    .dbam_to_cs  = f17_base_addr_to_cs_size,
                   ^~~~~~~~~~~~~~~~~~~~~~~~
                   f17_addr_mask_to_cs_size
make[2]: *** [scripts/Makefile.build:273: drivers/edac/amd64_edac.o] Error 1

make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:1076: drivers] Error 2
make: *** Waiting for unfinished jobs....

If it is any consolation: we have all done this mistake in a hurry at
least once in the past but pls do take your time.

Thx.

Leaving in the rest for reference for the newly CCed.
