In order to perform their duties, all LED callbacks need a pointer to the struct acpi_device representing the FUJ02E3 ACPI device. To limit the use of the module-wide pointer, the same pointer should be extracted from data that gets passed to LED callbacks as arguments. However, LED core does not currently support supplying driver-specific pointers to struct led_classdev callbacks, so the latter have to be implemented a bit differently than backlight device callbacks and platform device attribute callbacks. As the FUJ02E3 ACPI device is the parent device of all LED class devices registered by fujitsu-laptop, struct acpi_device representing the former can be extracted by following the parent link present inside the struct device belonging to the struct led_classdev passed as an argument to each LED callback. To get rid of module-wide structures defining LED class devices, allocate them dynamically using devm_kzalloc() and initialize them in acpi_fujitsu_laptop_leds_register().

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.
