The pci_save_state() call in vmd_suspend() can be performed by pci_pm_suspend_irq(). This also allows VMD to benefit from the call into pci_prepare_to_sleep(). The pci_restore_state() call in vmd_resume() was restoring state after pci_pm_resume()::pci_restore_standard_config() had already restored state. It's also been suspected that the config state should have been restored before re-requesting IRQs instead of afterwards. Remove the pci_save_state()/pci_restore_state() calls in vmd_suspend()/vmd_resume() to allow proper flow through generic PCI core Power Management 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.
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.
