Staging: comedi: serial2002: decrease stack usage
512 bytes of stack can be saved in serial_2002_open() by modifying 'struct config_t'. A short int suffices for the 'kind' and 'bits' members. (Actually, a char would suffice, but wouldn't save any more stack than a short int.) Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
