From 06f3d71ea071b70e62bcc146cd9ff7ed1f9d4e43 Mon Sep 17 00:00:00 2001 From: James Smart Date: Wed, 13 Mar 2019 18:55:01 +0100 Subject: nvme-fc: fix numa_node when dev is null A recent change added a numa_node field to the nvme controller and has the transport assign the node using dev_to_node(). However, fcloop registers with a NULL device struct, so the dev_to_node() call oops. Revise the assignment to assign no node when device struct is null.
