Public bug reported:

Latest megaraid_sas and mpt3sas adapters which support Resizable BAR
with 1 MB BAR size fails to initialize during system resume from S3
sleep.

state on resume")

We see that the same commit has been ported to UBUNTU18.X - PCI: Restore
resized BAR state on resume (bsc#1105355).
