help
This driver makes the mail LED accessible from userspace

known mode: off, blink at 0.5Hz and blink at 1Hz.
The driver supports two kinds of interface: using ledtrig-timer
or through /sys/class/leds/clevo::mail/brightness. As this LED
cannot change it's brightness it blinks instead. The brightness
value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
blink at 1Hz.
This module can drive the mail LED for the following notebooks:
Clevo D400P
Clevo D410J
Clevo D410V
Clevo D400V/D470V (not tested, but might work)
Clevo M540N
Clevo M5x0N (not tested, but might work)
Positivo Mobile (Clevo M5x0V)
If your model is not listed here you can try the "nodetect"
