Fixes the following W=1 kernel build warning(s):

 drivers/tty/n_gsm.c:525: warning: expecting prototype for gsm_stuff_packet(). Prototype was for gsm_stuff_frame() instead
 drivers/tty/n_gsm.c:1608: warning: expecting prototype for gsm_dlci_control(). Prototype was for gsm_dlci_command() instead
 drivers/tty/n_gsm.c:2561: warning: Function parameter or member 'cookie' not described in 'gsmld_read'
 drivers/tty/n_gsm.c:2561: warning: Function parameter or member 'offset' not described in 'gsmld_read'
