help
This option enables the use of the sleep LED as a hard drive
activity LED.
+ This option is deprecated, it only selects ADB_PMU_LED and
+ LEDS_TRIGGER_IDE_DISK and changes the code in the new led class
+ device to default to the ide-disk trigger (which should be set
+ from userspace via sysfs).
