Drivers that use dvb_attach can have just one exported symbol, or they will cause compilation breakages depending on the selected frontends. As Jim reported: drivers/built-in.o: In function `technisat_usb2_set_voltage': technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio' make: *** [vmlinux] Error 1 That happens because, on his configuration, the configuration is: CONFIG_DVB_USB=y CONFIG_DVB_STV090x=m Luis proposed ar way to fix, but that would just force the STV090x to be selected, even if one wants to use a device with a different frontend. Instead, let's do the right thing: move set_gpio to the configuration structure and fill it during dvb_attach(). This way, the driver can still call it, and dvb_attach() will load stv090x module only if the device really needs it.
