Subject: [PATCH v8 0/3] leds: trigger: implement a tty trigger
Date: Mon, 12 Oct 2020 14:33:55 +0200 [thread overview]
Message-ID: <20201012123358.1475928-1-u.kleine-koenig@pengutronix.de> (raw)
this is v8 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 v7 sent with Message-Id
20200707165958.16522-1-u.kleine-koenig@pengutronix.de on 7 Jul 2020:
- ensure the worker function doesn't monopolize the context it is
running in
- Add a missing mutex_unlock in an error path
Pavel Machek wondered in reply to v7 if led_set_brightness was a good
idea. I didn't understand the issue and didn't get a reply to my
question. So if this is indeed a problem, this one still persists.
Best regards
Uwe
