Is there any case where cp doesn't get assigned here? Either by
get_builtin_microcode() or by find_microcode_in_initrd()?

Who's "we" and how can "we" trace them? When I see Addresses-Coverity:
how can I trace how a fix is found? How can I find out what that tag
even means?

All I'm asking is to document how one can find out what that tag means
and how it can be used by people looking at that commit message.

Thx.
