Dear Baldwin,
Thanks for your support .but my pci probe function is not
getting called for my device id and vendor id. Because pccbb driver
already sets the device_set_desc as PCI-CardBus Bridge. So is there any
other option for me to make my_pciprobe function to be called for my
corresponding device id and vendor id.

Thanks,

Regards,
Bagavathy kumar .M

The pccbb driver returns BUS_PROBE_DEFAULT (it should probably return
GENERIC
in the case where it matches only on class codes). Your driver just
needs to
return a numerically higher value (but still < 0) to claim the device.
You
can probably use BUS_PROBE_VENDOR or BUS_PROBE_DEFAULT + 1.
