I believe maintaining the s-o-b is usually reserved for the case when the
patch only has minor edits; here your patch while same in spirit has
some 30 fewer lines. Maybe should use "From:" or mention Jussi in the
commit log to maintain attribution instead?

Would be good to expand this comment as to why (just copy another
sentence from the commit log or so).

Did you test that it did get lost over suspend/resume? A glance at
pci_save_pcie_state seems to indicate it's saved.
