[Why] LTTPR capable devices on the DisplayPort path may assume that extended LTTPR AUX timeouts will be used after LTTPR capabilities are read. When DPTX operates in non-LTTPR mode, AUX timeouts are not extended and this can result in AUX transactions timing out. [How] Use shared helper function to determine LTTPR mode and do not read LTTPR capabilities in non-LTTPR mode.

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.
