I don't think it has to be updated every time v4l-utils changes, at least for now, as long as it is clear which v4l-utils version is used. > >>> See each detailed section in the report below to find out the git URL and >>> particular revision that was used to build the test binaries. >>> >>> >>> Tree: media >>> Branch: master >>> Kernel: media_v5.1-2-16-gfc8670d1f72b >> >> I assume this is the version of the host kernel, right?

So the hashes are different, which led me to conclude that one referred to the host kernel and the other to the kernel under test.
