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.
