Since the DW PCIe common code now supports the IP-core version auto-detection there is no point manually setting the version up for the controllers newer than v4.70a. In particular Intel GW PCIe platform code can be set free from the manual version setup, which as a positive side effect causes the private device data removal too. Suggested-by: Rob Herring <robh@xxxxxxxxxx> Signed-off-by: Serge Semin <Sergey.Semin@xxxxxxxxxxxxxxxxxxxx> --- Folks, I don't have Intel GW PCIe hw instance to test it out. Could you please make sure this patch doesn't brake anything?
