There are several cases where events handled in one of the dell-* drivers need to be propagated to another dell-* driver. This commit adds 3 generic functions: dell_laptop_register_notifier() dell_laptop_unregister_notifier() dell_laptop_call_notifier() It currently only defines 1 action: DELL_LAPTOP_KBD_BACKLIGHT_BRIGHTNESS_CHANGED Which is intended to propagate kbd_backlight_brightness_changed wmi events from dell-wmi to dell-laptop (which contains the actual kbd backlight driver). These functions are put in dell-smbios as both dell-wmi and dell-laptop use smbios functions and I do not want to put the notifier head in either driver, as that will make the 2 drivers depend on each other.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
