From c9475cb0c358ff0dd473544280d92482df491913 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Mon, 7 Nov 2005 01:01:26 -0800 Subject: [PATCH] [PATCH] kfree cleanup: drivers/scsi This is the drivers/scsi/ part of the big kfree cleanup patch. Remove pointless checks for NULL prior to calling kfree() in drivers/scsi/.
