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.
135
136	  This module can drive the mail LED for the following notebooks:
137
138	  	Clevo D400P
139	  	Clevo D410J
140	  	Clevo D410V
141	  	Clevo D400V/D470V (not tested, but might work)
142	  	Clevo M540N
143	  	Clevo M5x0N (not tested, but might work)
144	  	Positivo Mobile (Clevo M5x0V)
145
146	  If your model is not listed here you can try the "nodetect"
147	  module paramter.
