------------------------------------------------------------------------ warning for section mismatch
WARNING: drivers/staging/comedi/drivers/cb_pcidio.o(.text+0x1c6): Section mismatch in reference from the function pcidio_attach() to the variable .devinit.rodata:pcidio_pci_table The function pcidio_attach() references the variable __devinitconst pcidio_pci_table. This is often because pcidio_attach lacks a __devinitconst annotation or the annotation of pcidio_pci_table is wrong.
