From 15755854d53b4bbb0bb37a0fce66f0156cfc8a17 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Thu, 20 Feb 2020 00:59:36 +0900 Subject: [PATCH] nvme: Fix uninitialized-variable warning gcc may detect a false positive on nvme using an unintialized variable if setting features fails. Since this is not a fast path, explicitly initialize this variable to suppress the warning.
