3.2.65-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Jan Kara <jack@xxxxxxx> commit 84ce0f0e94ac97217398b3b69c21c7a62ebeed05 upstream. When sg_scsi_ioctl() fails to prepare request to submit in blk_rq_map_kern() we jump to a label where we just end up copying (luckily zeroed-out) kernel buffer to userspace instead of reporting error. Fix the problem by jumping to the right label.
