From 10981f23a1b865290a5e21ad43a0f93710271cc6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 29 Nov 2022 10:51:05 +0100 Subject: [PATCH] nvme-pci: cleanup nvme_suspend_queue Remove the unused returne value, pass a dev + qid instead of the queue as that is better for the callers as well as the function itself, and remove the entirely pointless kerneldoc comment.
