[Buildroot] [PATCH v4 1/2] zbar: new package

[Vicente Olivert Riera <Vincent.Riera@imgtec.com>]

Dear Viacheslav Volkov,

you keep not marking the previous versions of your patches as superseded
in Patchwork. Is there a reason to not do that?

You ignored my comments about adding a description and a SoB to the
patch files.

In the propagated libv4l dependencies, the comment you add at the end of
each line says "lib4l". That's a typo, it should be "libv4l". Also the
line which says "# dependencies from lib4l" is not needed anymore.

Regarding the explanation for the ZBAR_INSTALL_FIXUP, it looks to me
that is a bug in the build system which could be fixed upstream. Have
you thought about reporting it upstream? Or write a patch to fix it and
send it upstream?

And one last thing. When a new version of a patch has significant
changes, you shouldn't keep the Reviewed-by from a previous version.

Regards,

Vincent.
