[ Upstream commit 932e1ba486 ]
The Medion Akoya E2215T's ACPI _LID implementation is quite broken:
1. For notifications it uses an ActiveLow Edge GpioInt, rather then
an ActiveBoth one, meaning that the device is only notified when the
lid is closed, not when it is opened.
2. Matching with this its _LID method simply always returns 0 (closed)
In order for the Linux LID code to work properly with this implementation,
the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN.
This commit adds a DMI quirk for this.

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.
