From 8168b9bba6a88fe8a81be5b5f0937faeb3f6775d Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 5 Feb 2015 10:38:19 +0300 Subject: [PATCH] UBI: block: Fix checking for NULL instead of IS_ERR() We recently switched from allocating ->rq using blk_init_queue() to use blk_mq_init_queue() so we need to update the error handling to check for IS_ERR() instead of NULL.
