The LEDs can only by turned on/off, so max_brightness should be set to 1. Without this the max_brightness sysfs-attribute will report 255 which is wrong. Signed-off-by: Hans de Goede <redacted> --- Changes in v3: - Use 1 instead of LED_ON Changes in v2: - New patch in v2 of this patch-set --- drivers/hid/hid-lenovo.c | 2 ++ 1 file changed, 2 insertions(+)
