  typos, warnings, correctness, and minor bugs.

  Specifics:

  dell-laptop:
     - add support for keyboard backlight.

  toshiba_acpi:
     - adaptive keyboard, hotkey, USB sleep and charge, and backlight
       updates.  Update sysfs documentation.

  toshiba_bluetooth:
     - fix enabling/disabling loop on recent devices

  apple-gmux:
     - lock iGP IO to protect from vgaarb changes

  other:
     - Fix typos, clear gcc warnings, clarify pr_* messages, correct
       return types, update MAINTAINERS"

Description:
This file allows to control the input triggers that
turn on the keyboard backlight illumination that is
disabled because of inactivity.
Read the file to see the triggers available. The ones
enabled are preceded by '+', those disabled by '-'.
To enable a trigger, write its name preceded by '+' to
this file. To disable a trigger, write its name preceded
by '-' instead.
For example, to enable the keyboard as trigger run:
echo +keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
To disable it:
echo -keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
Note that not all the available triggers can be configured.

Description:
This file allows to specify the interval after which the
keyboard illumination is disabled because of inactivity.
The timeouts are expressed in seconds, minutes, hours and
days, for which the symbols are 's', 'm', 'h' and 'd'
respectively.
To configure the timeout, write to this file a value along
with any the above units. If no unit is specified, the value
is assumed to be expressed in seconds.
For example, to set the timeout to 10 minutes run:
echo 10m > /sys/class/leds/dell::kbd_backlight/stop_timeout
Note that when this file is read, the returned value might be
expressed in a different unit than the one used when the timeout
was set.
Also note that only some timeouts are supported and that
some systems might fall back to a specific timeout in case
an invalid timeout is written to this file.
