Merge tag 'platform-drivers-x86-v3.19-2' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull platform driver fix from Darren Hart:
"Revert keyboard backlight sysfs support and documentation.
The support for the dell-laptop keyboard backlight was flawed and the
fix:
https://lkml.org/lkml/2015/1/14/539
was more invasive that I felt comfortable sending at RC5.
This series reverts the support for the dell-laptop keyboard backlight
as well as the documentation for the newly created sysfs attributes.
We'll get this implemented correctly for 3.20"

17 | Description: | ||
18 | This file allows to control the input triggers that | ||
19 | turn on the keyboard backlight illumination that is | ||
20 | disabled because of inactivity. | ||
21 | Read the file to see the triggers available. The ones | ||
22 | enabled are preceded by '+', those disabled by '-'. | ||
23 | |||
24 | To enable a trigger, write its name preceded by '+' to | ||
25 | this file. To disable a trigger, write its name preceded | ||
26 | by '-' instead. | ||
27 | |||
28 | For example, to enable the keyboard as trigger run: | ||
29 | echo +keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers | ||
30 | To disable it: | ||
31 | echo -keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers | ||
32 | |||
33 | Note that not all the available triggers can be configured. | ||

40 | Description: | ||
41 | This file allows to specify the interval after which the | ||
42 | keyboard illumination is disabled because of inactivity. | ||
43 | The timeouts are expressed in seconds, minutes, hours and | ||
44 | days, for which the symbols are 's', 'm', 'h' and 'd' | ||
45 | respectively. | ||
46 | |||
47 | To configure the timeout, write to this file a value along | ||
48 | with any the above units. If no unit is specified, the value | ||
49 | is assumed to be expressed in seconds. | ||
50 | |||
51 | For example, to set the timeout to 10 minutes run: | ||
52 | echo 10m > /sys/class/leds/dell::kbd_backlight/stop_timeout | ||
53 | |||
54 | Note that when this file is read, the returned value might be | ||
55 | expressed in a different unit than the one used when the timeout | ||
56 | was set. | ||
57 | |||
58 | Also note that only some timeouts are supported and that | ||
59 | some systems might fall back to a specific timeout in case | ||
60 | an invalid timeout is written to this file. | ||
