Why build empty object files in drivers/media?

[Chuck Ebbert]

I have this in my .config file for 2.6.13-rc3:


#
# Multimedia devices
#
# CONFIG_VIDEO_DEV is not set

#
# Digital Video Broadcasting Devices
#
# CONFIG_DVB is not set


And yet these completely empty files are being built:


$ find drivers/media -name built-in.o | xargs ls -go
-rw-rw-r--  1 305 Jul 16 00:20 drivers/media/built-in.o
-rw-rw-r--  1   8 Jul 16 00:20 drivers/media/common/built-in.o
-rw-rw-r--  1   8 Jul 16 00:20 drivers/media/dvb/b2c2/built-in.o

$ size drivers/media/built-in.o

      0       0       0       0       0 drivers/media/built-in.o
