Message-Id: <1301415401-23876-1-git-send-email-bp@amd64.org> Date: Tue, 29 Mar 2011 18:16:41 +0200 From: Borislav Petkov <bp@...64.org> To: <linux-edac@...r.kernel.org> Cc: <linux-kernel@...r.kernel.org>, Mauro Carvalho Chehab <mchehab@...hat.com>, Borislav Petkov <borislav.petkov@....com> Subject: [PATCH] amd64_edac: Fix potential memleak From: Borislav Petkov <borislav.petkov@....com> 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.
