Fix it to get rid of this compilation warning in the nvme-5.17 branch: drivers/nvme/host/core.c: In function ‘nvme_setup_cmd’: drivers/nvme/host/core.c:993:20: warning: unused variable ‘ctrl’ [-Wunused-variable] struct nvme_ctrl *ctrl = nvme_req(req)->ctrl; ^~~~ Fixes: 292ddf67bbd5 ("nvme: increment request genctr on completion") Signed-off-by: Geliang Tang Signed-off-by: Christoph Hellwig --- diff --git a/drivers/nvme/host/core.c b/drivers/nvme/host/core.c index 44c375a1edbb..9666c7bf4379 100644 --- a/drivers/nvme/host/core.c +++ b/drivers/nvme/host/core.c @@ -990,7 +990,6 @@ EXPORT_SYMBOL_GPL(nvme_cleanup_cmd); blk_status_t nvme_setup_cmd(struct nvme_ns *ns, struct request *req) { struct nvme_command *cmd = nvme_req(req)->cmd; - struct nvme_ctrl *ctrl = nvme_req(req)->ctrl; blk_status_t ret = BLK_STS_OK; if (!(req->rq_flags & RQF_DONTPREP))
