132	  This driver makes the mail LED accessible from userspace
133	  programs through the leds subsystem. This LED have three
134	  known mode: off, blink at 0.5Hz and blink at 1Hz.
135
136	  The driver supports two kinds of interface: using ledtrig-timer
137	  or through /sys/class/leds/clevo::mail/brightness. As this LED
138	  cannot change it's brightness it blinks instead. The brightness
139	  value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
140	  blink at 1Hz.
141
142	  This module can drive the mail LED for the following notebooks:
143
144	  	Clevo D400P
145	  	Clevo D410J
146	  	Clevo D410V
