Subject: [PATCH 3/4] nvme-pci: remove an extra queue reference
Date: Tue, 18 Oct 2022 15:57:19 +0200	[thread overview]
Message-ID: <20221018135720.670094-4-hch@lst.de> (raw)
In-Reply-To: <20221018135720.670094-1-hch@lst.de>

Now that blk_mq_destroy_queue does not release the queue reference, there
is no need for a second admin queue reference to be held by the nvme_dev.
