[PATCH 0/2] leds: ledtrig-tty: mode xtension

[Florian Eckert <fe@dev.tdt.de>]

The following patch set adds the possibility to change the tty trigger
modes. Until now, the LED is flashed when data is transmitted. With a
legacy serial interface there are additional signal lines.
If this line changes then the LED is turned on/off.

CTS: Clear To Send       -> DCE is ready to accept data from the DTE
DSR: Data Set Ready      -> DCE is ready to receive and send data.
CAR: Data Carrier Detect -> DCE is receiving a carrier from a remote DCE.
RNG: Ring Indicator      -> DCE has detected an incoming ring on the line.

  tty: new helper function tty_get_mget
  leds: trigger: ledtrig-tty: add additional modes
