From 18f91b3cd85d22b9090b0c6a3449e26a0eeb1be5 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Fri, 17 Apr 2020 15:12:07 +0800 Subject: [PATCH] nvme: Fix uninitialized-variable warning [ Upstream commit 15755854d53b4bbb0bb37a0fce66f0156cfc8a17 ] 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.
