Not all available options are present in .config. It is possible that
CONFIG_VIDEOBUF_GEN depends on another option that is not selected.

The best way in this case is to open the linux-menuconfig, type /
(slash) followed by a search string, for example VIDEOBUF_GEN. It
should show you at least one match, along with more details about:
- where is it in the menu structure
- which options does it depend on (and what is the current value of
these options, indicated with [=y], [=n] etc.

This should give you enough info to be able to select the option correctly.

Best regards,
Thomas
