I didn't pay attention, but in fact this is still not correct.

zbar selects libv4l, and libv4l has a dependency on headers >= 3.0. So
zbar should keep a dependency on >= 3.0, and so should the
gst-plugins-bad zbar option. Otherwise, you can enable zbar on < 3.0
headers, but libv4l is not selectable, violating the kconfig
correctness of the configuration.

Conclusion: we need a headers >= 3.0 dependency on zbar and the
gst-plugins-bad zbar option.

Could you fix this and resend ?

Thanks a lot!
