From 3ae279d25954de47c704ca713a2711ac10fcd1ee Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 9 Feb 2011 15:34:36 -0800 Subject: [SCSI] target: iblock/pscsi claim checking for NULL instead of IS_ERR blkdev_get_by_path() returns an ERR_PTR() or error and it doesn't return a NULL. It looks like this bug would be easy to trigger by mistake. Signed-off-by: Dan Carpenter Signed-off-by: Nicholas A.
