Instead of doing that for each call to pata_falcon_data_xfer(), I'd rather find the relevant bits from the module parameter at device probe time, and set the device-scope bit mask accordingly.
Good idea -- I see why you'd want to optimize pata_falcon_data_xfer(). But you don't need a device-scope bit mask, you need a device-scope bit, which could be obtained just by comparing private_data with NULL.
