A quick workaround is to disable the iptv driver from being built.
You can do this by running 'make menuconfig' before trying to build the driver and disabling Conexant cx23416/cx23415 MPEG encoder/decoder support.
Multimedia support ---> Video capture adapters ---> [ ] Conexant cx23416/cx23415 MPEG encoder/decoder support
Or you can manually edit v4l/.config and making sure it says
- Code: Select All Code
# CONFIG_VIDEO_IVTV is not set
