 126           This driver makes the mail LED accessible from userspace
 127           programs through the leds subsystem. This LED have three
 128           known mode: off, blink at 0.5Hz and blink at 1Hz.
 129
 130           The driver supports two kinds of interface: using ledtrig-timer
 131           or through /sys/class/leds/clevo::mail/brightness. As this LED
 132           cannot change it's brightness it blinks instead. The brightness
 133           value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
 134           blink at 1Hz.
