Jesper Juhl f9028317b2 Documentation: Add newline at end-of-file to files lacking one
This patch simply adds a newline character at end-of-file to those
files in Documentation/ that currently lack one.

This is done for a few different reasons:

A) It's rather annoying when you do "cat some_file.txt" that your
   prompt/cursor ends up at the end of the last line of output rather
   than on a new line.

B) Some tools that process files line-by-line may get confused by the
   lack of a newline on the last line.

C) The "\ No newline at end of file" line in diffs annoys me for some
   reason.

So, let's just add the missing newline once and for all.

will also show the brightness level stored for this
<ambient light zone>.

Description:
Control the dim brightness for <ambient light zone>
on this <backlight>. Values are between 0 and 127, typically
set to 0. Full off when the backlight is disabled.
This file will also show the dim brightness level stored for
this <ambient light zone>.

Description:
Get conversion value of the light sensor.
This value is updated every 80 ms (when the light sensor
is enabled). Returns integer between 0 (dark) and
8000 (max ambient brightness)
What: /sys/class/backlight/<backlight>/ambient_light_zone
Date: May 2011
KernelVersion: 3.0
Contact: device-drivers-devel@blackfin.uclinux.org
Description:
Get/Set current ambient light zone. Reading returns
integer between 1..5 (1 = daylight, 2 = bright, ..., 5 = dark).
Writing a value between 1..5 forces the backlight controller
to enter the corresponding ambient light zone.
Writing 0 returns to normal/automatic ambient light level
operation. The ambient light sensing feature on these devices
is an extension to the API documented in
Documentation/ABI/stable/sysfs-class-backlight.
It can be enabled by writing the value stored in
/sys/class/backlight/<backlight>/max_brightness to
/sys/class/backlight/<backlight>/brightness.
