Ard Biesheuvel c8a622ed9e ACPI / button: make module loadable when booted in non-ACPI mode
commit ac1e55b1fd upstream.

Modules such as nouveau.ko and i915.ko have a link time dependency on
acpi_lid_open(), and due to its use of acpi_bus_register_driver(),
the button.ko module that provides it is only loadable when booted in
ACPI mode. However, the ACPI button driver can be built into the core
kernel as well, in which case the dependency can always be satisfied,
and the dependent modules can be loaded regardless of whether the
system was booted in ACPI mode or not.

So let's fix this asymmetry by making the ACPI button driver loadable
as a module even if not booted in ACPI mode, so it can provide the
acpi_lid_open() symbol in the same way as when built into the kernel.

README

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.
