From 7860569ad47f9fbd7c9f93a5c2b7d2a18e4af831 Mon Sep 17 00:00:00 2001 From: Chaitanya Kulkarni Date: Sun, 13 Jun 2021 18:58:51 -0700 Subject: [PATCH] nvmet: remove local variable In function errno_to_nvme_status() we store the value of the NVMe status into the local variable and don't do anything useful with that but just return. Remove the local variable and return the value directly from switch. This also removed extra break statements.
