From 254beb84faccbe2f4eda0b51924857bdfb679969 Mon Sep 17 00:00:00 2001 From: James Smart Date: Thu, 21 Dec 2017 14:15:47 -0800 Subject: nvme-fcloop: avoid possible uninitialized variable warning The kbuild test robot send mail of a potential use of an uninitialized variable - "tport" in fcloop_delete_targetport() which then calls __targetport_unreg() which uses the variable. It will never be the case it is uninitialized as the call to __targetport_unreg() only occurs if there is a valid nport pointer. And at the time the nport pointer is assigned, the tport variable is set. Remove the warning by assigning a NULL value initially.
