As reported by the kbuild test robot <[email protected]>: drivers/built-in.o: In function `em28xx_dvb_init': em28xx-dvb.c:(.text+0x876f2c): undefined reference to `drx39xxj_attach' That happens when CONFIG_VIDEO_EM28XX_DVB is selected, and neither CONFIG_MEDIA_SUBDRV_AUTOSELECT or DVB_DRX39XYJ is selected.
