commitd823346876upstream. Commitcfae58ed68("platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE reporting on the HP stream x360 11 series on which it was previously broken by commitde9647efea("platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's"). It turns out that enabling SW_TABLET_MODE reporting on devices with a chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1 at boot on the HP Pavilion 11 x360, which causes libinput to disable the kbd and touchpad. The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection shows only one other model, the Medion E1239T ever setting bit 4 and it always sets this together with bit 6. So lets treat bit 4 as a second bit which when set indicates the device not being in tablet-mode, as we already do for bit 6. While at it also prefix all VGBS constant defines with "VGBS_".

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.
