[media] dib8000: export just one symbol
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. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
