From 2e1d4a065a77d076a679df22a4eddbc7e33cad98 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Tue, 29 May 2012 18:47:37 +0000 Subject: [PATCH] net/smsc911x: Repair broken failure paths Current failure paths attempt to free resources which we failed to request and disable resources which we failed to enable ones. This leads to kernel oops/panic. This patch does some simple re-ordering to prevent this from happening.
