From 3a73e8c7715cdf53c24b602bfca15ec54d7c989b Mon Sep 17 00:00:00 2001 From: Nate Dailey Date: Thu, 21 Apr 2005 16:14:05 -0400 Subject: [PATCH] [SCSI] drivers/scsi/sr_ioctl.c: check for failed allocation I noticed a case in sr_ioctl.c's sr_get_mcn where a buffer is allocated, but the pointer isn't checked for null.
