    Subject[PATCH] serial: silence section mismatch warnings in 8250_pci
    Date
    Fix following warnings:
    WARNING: drivers/serial/built-in.o(.data+0x5b8): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_ite887x_exit()
    WARNING: drivers/serial/built-in.o(.data+0x5e0): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_plx9050_exit()
    WARNING: drivers/serial/built-in.o(.data+0x608): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_plx9050_exit()
    WARNING: drivers/serial/built-in.o(.data+0x658): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_plx9050_exit()

    WARNING: drivers/serial/built-in.o(.data+0x6a8): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_plx9050_exit()
    WARNING: drivers/serial/built-in.o(.data+0x6d0): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:sbs_exit()
    WARNING: drivers/serial/built-in.o(.data+0x6f8): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:sbs_exit()
    WARNING: drivers/serial/built-in.o(.data+0x720): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:sbs_exit()
    WARNING: drivers/serial/built-in.o(.data+0x748): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:sbs_exit()

    pci_serial_quirks contains a number of function pointers
    where the referenced function is annotated __devexit.
    This is OK so we annotate pci_serial_quirks with
    __refdata to ignore the __devexit references
