[GIT PULL] LED updates for 4.11

[Jacek Anaszewski]

Hi Linus,

Please pull LED updates for 4.11 merge cycle.

New features and improvements:
- add new optional brightness_hw_changed attribute for the LEDs that
  may have their brightness level changed autonomously, (outside of
  kernel control) by hardware / firmware. The attribute supports
  userspace notifications through POLLPRI events
- add led_brightness_hw_mon tool that demonstrates how to use the
  aforementioned feature
- add LED_ON enum for LEDs that can be only turned on/off, and don't
  allow setting other brightness levels
- allow for adjusting heartbeat trigger blink brightness level

Fixes and cleanups:
- avoid harmless maybe-uninitialized warning in leds-ktd2692.c
- add context to the existing example entries in common LED bindings
  to make the documentation more clear

The following changes since commit 7ce7d89f48834cefece7804d38fc5d85382edf77:

  Linux 4.10-rc1 (2016-12-25 16:13:08 -0800)
