Subject: [025/105] amd64_edac: Fix potential memleak

2.6.38-stable review patch.  If anyone has any objections, please let us know.

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

From: Borislav Petkov <borislav.petkov@....com>

commit a9f0fbe2bbf328f869fc5ee5a12c6a4118c32689 upstream.

We check the pointers together but at least one of them could be invalid
due to failed allocation. Since we cannot continue if either of the two
allocations has failed, exit early by freeing them both.
