Because of brcmf_pcie_setup function also need the driver_data, so I tried to define
a global variable named NEED_SEED_FLAG. But marco define didn't allow to modify
value in it, do you think where is the best place to assign the flag? 

Or you still think should add a new macro named BRCMF_PCIE_DEVICE_NEED_SEED?
To be honest, I'm not quite sure which way is the best.
