PCI: Correct pci=resource_alignment parameter example
The "pci=resource_alignment" parameter is described as requiring an order (not a size) and the code in pci_specified_resource_alignment() expects an order. But the example wrongly shows a size. Convert the example to an order. Fixes: 8b078c603249 ("PCI: Update "pci=resource_alignment" documentation") Link: https://lore.kernel.org/r/20190606032557.107542-1-aik@ozlabs.ru Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
