Second generation keyboard backlight (type 2) laptops can switch on the keyboard LED on their own via hardware/firmware, but the LED subsystem is unaware of such change since the LED interface was only being created on first generation keyboard backlight (type 1) laptops. This patch creates the LED interface for second gen keyboards and calls the *_hw_changed API whenever userspace changes the state of the keyboard backlight LED. While we are at it, remove an unneeded asignment to the acpi_dev struct under *_kbd_bl_work, and also update the kbd_event_generated variable in the main toshiba struct instead of the global struct.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
