Commitde9647efea("platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's") added a DMI chassis-type check to avoid accidentally reporting SW_TABLET_MODE = 1 to userspace on laptops (specifically on the Dell XPS 9360), to avoid e.g. userspace ignoring touchpad events because userspace thought the device was in tablet-mode. But if we are not getting the initial status of the switch because the device does not have a tablet mode, then we really should not advertise the presence of a tablet-mode switch to userspace at all, as userspace may use the mere presence of this switch for certain heuristics.

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.
