Potential NULL pointer deference in scsi

Hi All: drivers/scsi/scsi.c: Inside function __starget_for_each_device(), dev_to_shost() could return NULL,however, the return value shost is not checked and get used. This could potentially be unsafe. -- Kind Regards, Yizhuo Zhai Computer Science, Graduate Student University of California, R
