[PATCH v2 0/3] PCI: Universal error recoverability of devices

[Lukas Wunner]

This series intends to replace commit 1dc302f7fccc ("PCI: Ensure error
recoverability at all times") on the pci/err topic branch:

https://git.kernel.org/pci/pci/c/1dc302f7fccc

The commit is assigning "dev->state_saved = false" in pci_bus_add_device()
and during review there were requests to explain the assignment more
clearly in a code comment.

However the assignment is (only) necessitated by missing assignments in
pci_legacy_suspend() and pci_pm_freeze(), so I propose to instead add
*those* assignments (patch [1/3]) and thus avoid the need for the
assignment in pci_bus_add_device(), together with its code comment.

Furthermore the commit is *removing* an assignment in pci_device_add().
I am separating that out to new patch [2/3].

So patch [3/3] is identical to the commit, but without the addition
of an assignment in pci_bus_add_device() and without the removal
of an assignment in pci_device_add().

I am looking into improving the documentation on pci_save_state()
in a separate series.
