[ Upstream commit 0dbbf25561b29ffab5ba6277429760abdf49ceff ] If we cannot communicate with the EC chip to detect the protocol version and its features, it's very likely useless to continue. Else we will commit all kind of uninformed mistakes (using the wrong protocol, the wrong buffer size, mixing the EC with other chips).

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.
