Dmitry Torokhov 0e45a09a1d Input: serio - define serio_pause_rx guard to pause and resume serio ports 
serio_pause_rx() and serio_continue_rx() are usually used together to
temporarily stop receiving interrupts/data for a given serio port.
Define "serio_pause_rx" guard for this so that the port is always
resumed once critical section is over.

Example:

	scoped_guard(serio_pause_rx, elo->serio) {
		elo->expected_packet = toupper(packet[0]);
		init_completion(&elo->cmd_done);
	}
