Hi Randy & Joe,
   I have seen the drivers/tty/n_gsm.c. 
>From line 529 to line 540 in drivers/tty/n_gsm.c like following.

529 static void hex_packet(const unsigned char *p, int len)
530 {
531	int i;
532	for (i = 0; i < len; i++) {
533		if (i && (i % 16) == 0) {
534			pr_cont("\n");
535			pr_debug("");                                                                      
536		}
537		pr_cont("%02X ", *p++);
538	}
539	pr_cont("\n");
540 }

Should we need the line 535? If true, i wanna the function of 
'pr_debug("");'

Thanks.
Harry Wei.
