Message-Id: <20170210182906.1468.77665.stgit@ltcalpine2-lp14.aus.stglabs.ibm.com> Date: Fri, 10 Feb 2017 13:29:06 -0500 From: Nathan Fontenot <nfont@...ux.vnet.ibm.com> To: netdev@...r.kernel.org Cc: jallen@...ux.vnet.ibm.com, tlfalcon@...ux.vnet.ibm.com Subject: [PATCH] ibmvnic: Call napi_disable instead of napi_enable in failure path The failure path in ibmvnic_open() mistakenly makes a second call to napi_enable instead of calling napi_disable. This can result in a BUG_ON for any queues that were enabled in the previous call to napi_enable.
