[ Upstream commit 2c9b7f8772033cc8bafbd4eefe2ca605bf3eb094 ] A caller of pm_genpd_init() that provides some states for the genpd via the ->states pointer in the struct generic_pm_domain, should also provide a governor. This because it's the job of the governor to pick a state that satisfies the constraints. Therefore, let's print a warning to inform the user about such bogus configuration and avoid to bail out, by instead picking the shallowest state before genpd invokes the ->power_off() callback.

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.
