[ Upstream commit a231224a601c1924b9df620281ad04472900d75f ] Ideapads for "Lenovo Yoga 3 Pro 1370" and "ZhaoYang K4e-IML" do not use EC to switch touchpad. Reading VPCCMD_R_TOUCHPAD will return zero thus touchpad may be blocked unexpectedly.

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.
