From ed5302d3c25006a9edc7a7fbea97a30483f89ef7 Mon Sep 17 00:00:00 2001 From: Liu Yuan Date: Tue, 19 Apr 2011 13:47:58 +0200 Subject: [PATCH] block, blk-sysfs: Fix an err return path in blk_register_queue() We do not call blk_trace_remove_sysfs() in err return path if kobject_add() fails. This path fixes it.
