The PCI port driver saves the PCI state after initializing the device with the applicable service devices. This was, however, before the service drivers were even registered because PCI probe happens before the device_initcall initialized those service drivers. The config space state that the services set up were not being saved. The end result would cause PCI devices to not react to events that the drivers think they did if the PCI state ever needed to be restored. Fix this by changing the service drivers from using the init calls to having the portdrv driver calling the services directly. This will get the state saved as desired, while making the relationship between the port driver and the services under it more explicit in the code.

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.
