From 6826ee4fdbe24c7aab56ce833ef94be81d190587 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Fri, 20 Jul 2007 16:50:10 -0500 Subject: [PATCH] [SCSI] bsg: fix bsg_register_queue error path unfortunately, if IS_ERR(class_dev) is true, that means class_dev isn't null and the check in the error leg is pointless ... it's also asking for trouble to request unregistration of a device we haven't actually created (although it works currently). Fix by using explicit gotos and unregisters.
