Your commit:

    [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.
