From c9bdad3c819cf63e2acea9994d2a60f23f1b7dd5 Mon Sep 17 00:00:00 2001 From: Mike Marciniszyn Date: Thu, 28 Mar 2013 18:17:20 +0000 Subject: [PATCH] IB/qib: Correct qib_verbs_register_sysfs() error handling qib_verbs_register_sysfs() never cleans up from a failure. Additionally, the caller of qib_verbs_register_sysfs() doesn't return the correct "ret" value. This patch resolves both of those issues.
