There are only two users of struct pci_platform_pm_ops in the tree, one of which is Intel MID PM and the other one is ACPI. They are mutually exclusive and the MID PM should take precedence when they both are enabled, but whether or not this really is the case hinges on the specific ordering of arch_initcall() calls made by them. The struct pci_platform_pm_ops abstraction is not really necessary for just these two users, but it adds complexity and overhead because of retoplines involved in using all of the function pointers in there. It also makes following the code a bit more difficult than it would be otherwise. Moreover, Intel MID PCI PM doesn't even implement the majority of the function pointers in struct pci_platform_pm_ops in a meaningful way, so switch over the PCI core to calling the relevant MID PM routines, mid_pci_set_power_state() and mid_pci_set_power_state(), directly as needed and drop mid_pci_platform_pm.

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.
