From c7a841f3aca469187db76842676951a672fd27d1 Mon Sep 17 00:00:00 2001 From: James Smart Date: Sun, 14 Nov 2010 11:12:04 -0500 Subject: [PATCH] [SCSI] bsg: correct fault if queue object removed while dev_t open This patch corrects an issue in bsg that results in a general protection fault if an LLD is removed while an application is using an open file handle to a bsg device, and the application issues an ioctl. The fault occurs because the class_dev is NULL, having been cleared in bsg_unregister_queue() when the driver was removed. With this patch, a check is made for the class_dev, and the application will receive ENXIO if the related object is gone.
