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.

The pm_runtime_force_suspend|resume() helpers currently requires the device to at some level (PM domain, bus, etc), have the ->runtime_suspend|resume() callbacks assigned for it, else -ENOSYS is returned as an error. However, there are no reason for this requirement, so let's simply remove it by allowing these callbacks to be NULL. Signed-off-by:Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by:
