Subject: [PATCH AUTOSEL 5.5 49/66] nvme: Fix uninitialized-variable warning
From: Keith Busch <kbusch@...nel.org>
[ 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.
