So I have this there:

/* This has to go after the PCI subsystem */
fs_initcall(init_amd_nbs);

as I need PCI. It itself does

arch_initcall(pci_arch_init);

so I guess init_amd_nbs() could be a subsys_initcall...

Or why is

subsys_initcall(dw_i2c_init_driver);

a subsys initcall in the first place?

Looking at

104522806a7d ("i2c: designware: dw_i2c_init_driver as subsys initcall")

I don't see a particular reason why it should be a subsys_initcall...

In any case, this should be fixed without an export which was crap in
the first place.

Hm.
