Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. This driver makes use of PCI helper functions like pci_save/restore_state(), pci_disable_device() and pci_set_power_state() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use to_pci_dev() to get "struct pci_dev*" variable. Compile-tested only. Maintainer has tested the changes on non-PowerPC platform and got no failure of the suspend/resume operations.

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 reStructuredText 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.
