[ Upstream commit1fac39fd03] 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. Some devices with a detachable keyboard and using the intel-vbnt (INT33D6) interface to report if they are in tablet mode (keyboard detached) or not, report 32 / "Detachable" as chassis-type, e.g. the HP Pavilion X2 series. Other devices with a detachable keyboard and using the intel-vbnt (INT33D6) interface to report SW_TABLET_MODE, report 8 / "Portable" as chassis-type. The Dell Venue 11 Pro 7130 is an example of this. Extend the DMI chassis-type check to also accept Portables and Detachables so that the intel-vbtn driver will report SW_TABLET_MODE on these devices. Note the chassis-type check was originally added to avoid a false-positive tablet-mode report on the Dell XPS 9360 laptop. To the best of my knowledge that laptop is using a chassis-type of 9 / "Laptop", so after this commit we still ignore the tablet-switch for that chassis-type.

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.
