Use gpiod_set_value_cansleep in the init_device function. Without this change, the driver may print a warning if the LP55xx enable pin is connected to a GPIO chip which can sleep (e.g. a GPIO expander): WARNING: CPU: 0 PID: 2719 at drivers/gpio/gpiolib.c:3051 gpiod_set_value+0x64/0xbc Signed-off-by: Stefan Eichenberger <eichest@xxxxxxxxx> --- drivers/leds/leds-lp55xx-common.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/leds/leds-lp55xx-common.c b/drivers/leds/leds-lp55xx-common.c index 77bb26906ea6e..8e7074f0fee00 100644 --- a/drivers/leds/leds-lp55xx-common.c +++ b/drivers/leds/leds-lp55xx-common.c @@ -442,9 +442,9 @@ int lp55xx_init_device(struct lp55xx_chip *chip) gpiod_direction_output(pdata->enable_gpiod, 0); gpiod_set_consumer_name(pdata->enable_gpiod, "LP55xx enable"); - gpiod_set_value(pdata->enable_gpiod, 0); + gpiod_set_value_cansleep(pdata->enable_gpiod, 0); usleep_range(1000, 2000); /* Keep enable down at least 1ms */ - gpiod_set_value(pdata->enable_gpiod, 1); + gpiod_set_value_cansleep(pdata->enable_gpiod, 1); usleep_range(1000, 2000); /* 500us abs min. */ } -- 2.39.2
