From e3f2a9cc84d35fac73c906de57ad3b3f5ff82008 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Sat, 18 Aug 2012 15:20:38 -0400 Subject: [SCSI] st: clean up dev cleanup in st_probe MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit st_probe leaves a cdev pointer hanging around that is compared during the error path and freed later. There's no need for the pointer to hang around at all. So we free it immediately and simplify the error handling.
