Hi
Bellow i explain simple method used only for research purpose used as
countermeasure in order to run MODULE_DEVICE_TABLE macro whithout .ko file,
just fixing stringfy problems ,like:

ld: drivers/usb/host/ehci-pci.o:(.rodata+0x0): multiple definition of
`__mod_pci__pci_ids_device_table';
drivers/tty/serial/8250/8250_mid.o:(.rodata+0x0): first defined here
ld: drivers/usb/host/ohci-pci.o:(.rodata+0x0): multiple definition of
`__mod_pci__pci_ids_device_table';
drivers/tty/serial/8250/8250_mid.o:(.rodata+0x0): first defined here
