The following commit cause a regression on ATI chipsets. 'commite788787ef4("usb:xhci:Add quirk for Certain failing HP keyboard on reset after resume")' This causes pinfo->smbus_dev to be wrongly set to NULL on systems with the ATI chipset that this function checks for first. Added conditional check for AMD chipsets to avoid the overwriting pinfo->smbus_dev.

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.
