[ Upstream commit aa2f9c12821e6a4ba1df4fb34a3dbc6a2a1ee7fe ] The ALC3263 codec on the XPS 13 9343 is also found on the Latitude 13 7350 and Venue 11 Pro 7140. They require the same handling for the combo jack to work with a headset: GPIO pin 6 must be set. The HDA driver always sets this pin on the ALC3263, which it distinguishes by the codec vendor/device ID 0x10ec0288 and PCI subsystem vendor ID 0x1028 (Dell). The ASoC driver does not use PCI, so adapt this check to use DMI to determine if Dell is the system vendor.

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.
