To prevent using module-wide data in backlight-related code, employ acpi_driver_data() and bl_get_data() where possible to fetch device-specific data to work on in each function. This makes the input local variable in acpi_fujitsu_bl_notify() and the acpi_handle field of struct fujitsu_bl redundant, so remove them.

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.
