21 need this to do anything useful with LEDs. If unsure, say N.
27 This option enables the flash LED sysfs class in /sys/class/leds.
28 It wraps LED Class and adds flash LEDs specific sysfs attributes
37 This option enables the multicolor LED sysfs class in /sys/class/leds.
40 for multicolor LEDs that are grouped together. This class is not
