Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.
The bug happens when:
CONFIG_DVB_DIB8000=m
CONFIG_DVB_USB_DIB0700=y
As a bonus, dib8000 won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.
Tested with both Pixelview PV-D231 and MyGica S870.
