From 3eb14ea8d9584e96680729c2c7a9129bafa13a39 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Mon, 3 Aug 2015 11:36:26 +0800 Subject: [PATCH] igb: Fix a deadlock in igb_sriov_reinit When igb_init_interrupt_scheme in igb_sriov_reinit is failed, the lock acquired by rtnl_lock() is not released, which causes a deadlock. This patch adds rtnl_unlock() in error handling to fix it.
