RussianNeuroMancer reported that the Intel 7265 wifi on a Dell Venue 11 Pro 7140 table stopped working after wakeup from suspend and bisected the problem to9ab105deb6("PCI/ASPM: Disable ASPM L1.2 Substate if we don't have LTR"). David Ward reported the same problem on a Dell Latitude 7350. Afteraf8bb9f898("PCI/ACPI: Request LTR control from platform before using it"), we don't enable LTR unless the platform has granted LTR control to us. In addition, we don't notice if the platform had already enabled LTR itself. After9ab105deb6("PCI/ASPM: Disable ASPM L1.2 Substate if we don't have LTR"), we avoid using LTR if we don't think the path to the device has LTR enabled. The combination means that if the platform itself enables LTR but declines to give the OS control over LTR, we unnecessarily avoided using ASPM L1.2.

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.
