platform/x86: asus-wmi: Fix SW_TABLET_MODE always reporting 1 on many different models
Commit b0dbd97de1f1 ("platform/x86: asus-wmi: Add support for SW_TABLET_MODE") added support for reporting SW_TABLET_MODE using the Asus 0x00120063 WMI-device-id to see if various transformer models were docked into their keyboard-dock (SW_TABLET_MODE=0) or if they were being used as a tablet. The new SW_TABLET_MODE support (naively?) assumed that non Transformer devices would either not support the 0x00120063 WMI-device-id at all, or would NOT set ASUS_WMI_DSTS_PRESENCE_BIT in their reply when querying the device-id. Unfortunately this is not true and we have received many bug reports about this change causing the asus-wmi driver to always report SW_TABLET_MODE=1 on non Transformer devices. This causes libinput to think that these are 360 degree hinges style 2-in-1s folded into tablet-mode. Making libinput suppress keyboard and touchpad events from the builtin keyboard and touchpad. So effectively this causes the keyboard and touchpad to not work on many non Transformer Asus models. This commit fixes this by using the existing DMI based quirk mechanism in asus-nb-wmi.c to allow using the 0x00120063 device-id for reporting SW_TABLET_MODE on Transformer models and ignoring it on all other models.

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.
