[PATCH v4 0/3] tty/leds: implement a trigger for ttys

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

Hello,

v3 of this series was sent earlier today starting with Message-Id:
20191217150736.1479-1-u.kleine-koenig@xxxxxxxxxxxxxx.

v4 only changes patch 3 dropping a few printks, fixing the show callback
for the dev attribute to match its store function. And I moved
ledtrig_tty_restart() into the already existing if (tty) {...} block in
dev_store and dropped the same check from the former function.

Best regards
Uwe
