Subject[PATCH 4.9 36/87] EDAC, amd64: Save and return err code from probe_one_instance()
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yazen Ghannam <Yazen.Ghannam@amd.com>


[ Upstream commit 2287c63643f0f52d9d5452b9dc4079aec0889fe8 ]

We should save the return code from probe_one_instance() so that it can
be returned from the module init function. Otherwise, we'll be returning
the -ENOMEM from above.
