leds: ledtrig-tty: Make rx tx activitate configurable
Until now, the LED blinks when data is sent via the tty (rx/tx).
This is not configurable.
This change adds the possibility to make the indication for the direction
of the transmitted data independently controllable via the new rx and
tx sysfs entries.
- rx:
Signal reception (rx) of data on the named tty device.
If set to 0, the LED will not blink on reception.
If set to 1 (default), the LED will blink on reception.
- tx:
Signal transmission (tx) of data on the named tty device.
If set to 0, the LED will not blink on transmission.
If set to 1 (default), the LED will blink on transmission.
This new sysfs entry are on by default. Thus the trigger behaves as
before this change.
