Dear Baldwin,
Thanks for your support =2Ebut my pci probe function is not
getting called for my device id and vendor id=2E Because pccbb driver
already sets the device_set_desc as PCI-CardBus Bridge=2E So is there any
other option for me to make my_pciprobe function to be called for my
corresponding device id and vendor id=2E
Thanks,
Regards,
Bagavathy kumar =2EM

The pccbb driver returns BUS_PROBE_DEFAULT (it should probably return
GENERIC=20
in the case where it matches only on class codes)=2E Your driver just
needs to=20
return a numerically higher value (but still < 0) to claim the device=2E
You=20
can probably use BUS_PROBE_VENDOR or BUS_PROBE_DEFAULT + 1=2E
--=20
