Intel DG2 discrete graphics PCIe endpoints advertise L1 acceptable exit latency to be < 1us even though they can actually tolerate unlimited exit latencies just fine. Quirk the L1 acceptable exit latency for these endpoints to be unlimited so ASPM L1 can be enabled.

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.
