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.
