Hi Philipp!

"from offset" means we use standard PCIe defines for registers that are
adjacent to Capabilities Register, and we reference them from the offset
at Capabilities Register.

No, all registers replaced are in use, unused in that context means they
(the custom-defined registers which can be referenced starting from
Capabilities Register address) become unused after the change, only.

Thanks for the capitalization catch. Unfortunately there's little I can do
now that Mani went ahead and applied the first two patches (directly
related to PCI subsystem).

Thanks,
