The intent with walking the gpd_list via calling genpd_present() from genpd_syscore_switch(), is to make sure the dev->pm_domain pointer belongs to a registered genpd. However, as a genpd can't be removed if there is a device attached to it, let's convert to use the quicker dev_to_genpd_safe() instead. Due to the above change, this allows us to clean up genpd_present() and move it inside CONFIG_PM_GENERIC_DOMAINS_OF, so let's do that as well.

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.
