I think in order to address Bjorn's concern, you should modify make sure
that the keystone and imx6 drivers that call hook_fault_code() do it
the same way. I think imx6 already does, but keystone does not, so
please send a patch for it, explaining why it's needed.

Conversely, I think the other dw-pcie based drivers should be changed
not to use an __init annotation at all, and instead use
module_platform_driver().
