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.
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
