Exporting functions for hardware filter is a bad idea, as it breaks compilation if: CONFIG_DVB_USB_AF9035=y CONFIG_DVB_AF9033=m Because the PID filter function calls would be hardcoded at af9035. The same doesn't happen with af9033_attach() because the dvb_attach() doesn't hardcode it. Instead, it dynamically links it at runtime. However, calling dvb_attach() multiple times is problematic, as it increments module kref. So, the better is to pass one parameter for the af9033 module to fill the hardware filters, and then use it inside af9035.
