Lenovo use two different trackpoints in the fifth generation Thinkpad X1 Carbon. Both are accessible over SMBUS/RMI but the pnpIDs are missing. This patch is for the Elantech trackpoint specifically which also reports SMB version 3 so rmi_smbus needs to be updated in order to handle it. For the record, I was not the first one to come up with this patch as it has been floating around the internet for a while now. However, I have spent significant time with testing and my efforts to find the original author of the patch have been unsuccessful.

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.
