Subject[PATCH v6 0/4] leds: trigger: implement a tty trigger
Date
From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

Hello,

This is v6 of my quest to introduce ledtriggers for UARTs. The previous
series is available at

http://lore.kernel.org/r/20191219093947.15502-1-u.kleine-koenig@pengutronix.de

The changes compared to that are that parsing of the dev parameter is
more strict and that I set brightness directly from the kworker instead
of using led_blink_set_oneshot which makes use of another kworker. (Both
requested by Pavel Machek.)

For the former I introduced a new helper kstrtodev_t() in the spirit of
kstrtoul() to implement the stricter parsing (instead of the lax one
using plain sscanf() in v5).

Best regards
Uwe
