[Qemu-devel] [PATCH v2 1/6] machine: export register_compat_prop()

[Peter Xu <peterx@redhat.com>]

We have HW_COMPAT_*, however that's only binded to machines, not other
things (like accelerators).  Behind it, it was register_compat_prop()
that played the trick.  Let's export the function for further use
outside HW_COMPAT_* magic.
