Arvid Norlander a63054e677 platform/x86: toshiba_acpi: Add quirk for buttons on Z830
[ Upstream commit 23f1d8b47d125dcd8c1ec62a91164e6bc5d691d0 ]

The Z830 has some buttons that will only work properly as "quickstart"
buttons. To enable them in that mode, a value between 1 and 7 must be
used for HCI_HOTKEY_EVENT. Windows uses 0x5 on this laptop so use that for
maximum predictability and compatibility.

As there is not yet a known way of auto detection, this patch uses a DMI
quirk table. A module parameter is exposed to allow setting this on other
models for testing.

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.
