From 96ef1be53663a9343dffcf106e2f1b59da4b8799 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 8 Nov 2022 09:10:21 +0100 Subject: [PATCH] nvme-pci: put the admin queue in nvme_dev_remove_admin Once the controller is shutdown no one can access the admin queue. Tear it down in nvme_dev_remove_admin, which matches the flow in the other drivers.
