[ Upstream commitafdd1ebb72] When FUJITSU_LAPTOP is enabled and NEW_LEDS is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for LEDS_CLASS Depends on [n]: NEW_LEDS [=n] Selected by [y]: - FUJITSU_LAPTOP [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && ACPI [=y] && INPUT [=y] && BACKLIGHT_CLASS_DEVICE [=y] && (ACPI_VIDEO [=n] || ACPI_VIDEO [=n]=n) The reason is that FUJITSU_LAPTOP selects LEDS_CLASS without depending on or selecting NEW_LEDS while LEDS_CLASS is subordinate to NEW_LEDS. Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

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.
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.
