commitc00054f540upstream. Previously we programmed the LTR_L1.2_THRESHOLD in the parent (upstream) device using the capability pointer of the *child* (downstream) device, which corrupted some random word of the parent's config space. Use the parent's L1 SS capability pointer to program its LTR_L1.2_THRESHOLD.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
