The one I sent has a memory leak but it won't matter for basic testing.
Or you can change the final bit to

        scsi_normalize_sense((char *)sense, sizeof(*sense), &sshdr);

        if (zebedee != cgc->buffer) {
                if (cgc->data_direction == DMA_FROM_DEVICE)    
                        memcpy(cgc->buffer, zebedee, cgc->buflen);
                kfree(zebedee); /* Time for bed */        
        }
