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).
