In case no_pci is configured, other buses e.g. fslmc bus will

You are enabling vfio_pci.
This part could stay conditionned by no_pci.
I was thinking you need vfio without vfio_pci. Am I right?
yes
If yes, I suggest to enable only vfio root module.
vfio_enable should be done only once. So, if I enable it for "vfio",
pci_vfio_enable is not required.
In any case it is not storing any PCI specific data and there are no
error checks here of "vfio_pci" enable failure.
So, if we use,
vfio_enable("vfio");
vfio_enabled |= vfio_is_enabled("vfio");
It seems no_pci check will not have any value.
let me know your thoughts?
