From 618cff4285dc0ef6ebb99f715116e7af62565293 Mon Sep 17 00:00:00 2001 From: Chaitanya Kulkarni Date: Thu, 10 May 2018 02:46:30 -0400 Subject: nvmet: remove duplicate NULL initialization for req->ns Remove the duplicate NULL initialization for req->ns. req->ns is always initialized to NULL in nvmet_req_init(), so there is no need to reset it later on failures unless we have previously assigned a value to it.
