Two of the files that are candidates for conversion to tristate from bool are: drivers/pci/host/pci-imx6.c drivers/pci/host/pci-keystone.c However, doing the conversion reveals that they are going to fail at modpost time since hook_fault_code isn't currently exported. Since we are now going to export it we also need to remove the __init tag, as the fcn needs to be present at insmod time.
