The state_saved flag tells the PCI core whether a driver assumes responsibility to save Config Space and put the device into a low power state on suspend. The flag is currently initialized to false on enumeration, even though it already is false (because struct pci_dev is zeroed by kzalloc()) and even though it is set to false before commencing the suspend sequence (the only code path where it's relevant). The flag is also set to false in pci_pm_thaw(), i.e. on resume, when it's no longer relevant. Drop these two superfluous flag assignments for simplicity.

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.
