This should be a PCI quirk shouldn't it?

Also:

> +	pci_disable_link_state(pdev, PCIE_LINK_STATE_L0S | PCIE_LINK_STATE_L1 |
> +		PCIE_LINK_STATE_CLKPM);

This is terrible formatting, you must line up the "PCIE_LINK_STATE_CLKPM" on
the second line with the very first column after the openning parenthesis
on the first line.
