From 1287dabd345f447bbe0f7a99fc95ab89bcfc0f5d Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 13 May 2013 22:29:04 +0800 Subject: NVMe: fix error return code in nvme_submit_bio_queue() nvme_submit_flush_data() might overwrite the initialisation of the return value with 0, so move the -ENOMEM setting close to the usage.
