So what was wrong with the suggested interface, ie having something like

	pci_clear_error(pdev);
	x = pci_inw_check(pdev, port);
	pci_outw_check(pdev, x | BIT, port);
	error = pci_check_error(pdev);

(or whatever.. I don't care about the names, but what I do _not_ want to
have is something that checks synchronously with the IO. To me, the
important part is that there is a separate "check errors" phase _after_
the IO has been completed, which is the one that ends up possibly waiting
for the posted writes to have actually gone to the device etc).
