| Subject: nvme: Fix uninitialized-variable warning |
| |
| From: Keith Busch <kbusch@kernel.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. |
