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
============
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.
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.
