Replace msleep() with usleep_range() in sun50i_a100_ledc_suspend() to address the checkpatch.pl warning. msleep() for such short delay can lead to inaccurate sleep times. Switch to usleep_range() provide more precise delay. Fix the following warning from checkpatch.pl: WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.rst + msleep(1); Signed-off-by: Abhishek Tamboli <abhishektamboli9@xxxxxxxxx> --- drivers/leds/leds-sun50i-a100.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/leds/leds-sun50i-a100.c b/drivers/leds/leds-sun50i-a100.c index 119eff9471f0..4c468d487486 100644 --- a/drivers/leds/leds-sun50i-a100.c +++ b/drivers/leds/leds-sun50i-a100.c @@ -368,7 +368,7 @@ static int sun50i_a100_ledc_suspend(struct device *dev) if (!xfer_active) break; - msleep(1); + usleep_range(1000, 1100); } clk_disable_unprepare(priv->mod_clk); -- 2.34.1
