x86 ACPI devices which ship with only Android as their factory image use older kernels which do not yet support ACPI serdev enumeration, as such the serdev information in their ACPI tables is not reliable. For example on the Asus ME176C tablet the serdev describing the Bluetooth HCI points to the serdev_controller connected to the GPS and the other way around. Use the new acpi_quirk_skip_serdev_enumeration() helper to identify known boards with this issue and then either abort adding the serdev controller (creating a tty cdev instead) or only create the controller leaving the instantation of the serdev itself up to platform code. In the case where only the serdev controller is created the necessary serdevs will instead be instantiated by the drivers/platform/x86/x86-android-tablets.c kernel module.

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.
