Subject: [PATCH v2 4/7] amd64_edac: enforce synchronous probe

From: "Luis R. Rodriguez" <mcgrof@...e.com>

While testing asynchronous PCI probe on this driver I noticed it failed
so enforce just synchronouse probe for now.  Asynchronous probe is not
used by default and requires userepace intervention.  Patches for its
support will be merged later.

The reason async probe fails is that the init call for this driver
relies on probe to have finished for at least one device. This needs to
be addressed before enabling async probe.
