The CIS contains the IRQ, ioport-range, voltage information etc
like the PCI config space.
So I think it is not copyrightable.
but Sierra Wireless provided this CIS by GPL.

The reason for the CIS update is original CIS does not conform to the pcmcia spec,
not forget to burn the CIS.

Actually, not all Sierra Wireless card need the CIS update.

Could you remove the PCMCIA_DEVICE_CIS_PROD_ID12 and PCMCIA_DEVICE_CIS_MANF_CARD
definition of the Sierra Wireless card,
and check the AC860 works or not?
