Subject: [PATCH v7 0/3] leds: trigger: implement a tty trigger
Date: Tue, 7 Jul 2020 18:59:55 +0200 [thread overview]
Message-ID: <20200707165958.16522-1-u.kleine-koenig@pengutronix.de> (raw)
Hello,
this is v7 of a series adding support for tty triggers. See patch 3 for
how to use it. The first two patches provide the necessary
infrastructure in the tty subsystem to make the trigger possible.
Changes compared to v6 sent with Message-Id:
20200213091600.554-1-uwe@kleine-koenig.org on 13 Feb 2020:
- use the tty's name instead of its major:minor
- drop kstrtodev_t helper
- retry opening the tty in case it only appears after it was configured
in the trigger
Uwe Kleine-König (3):
tty: rename tty_kopen() and add new function tty_kopen_shared()
tty: new helper function tty_get_icount()
leds: trigger: implement a tty trigger
