From 9f173b33843552c48e0136e02e7362c8229c8e57 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 5 Nov 2014 23:39:09 +0300 Subject: [PATCH] NVMe: blk_mq_alloc_request() returns error pointers We recently converted this to blk_mq but the error checks have to be updated to check for IS_ERR() instead of NULL.
