Currently the v4l2-tracer autogeneration script is run by meson. If the script gets confused by changes to the latest kernel headers, then the v4l2-tracer won’t compile. And, even worse, the autogeneration script will have overwritten the autogenerated files so there is no history of the changes that broke the compilation. This series solves the problem by adding the autogenerated files to the git repository. It stops using meson to create the files and instead, patches the v4l2-tracer whenever v4l-utils is synced with the latest kernel headers. If compilation breaks, it is easy to fix by just removing the v4l2-tracer patches before committing the other changes related to the sync. Changes in v3: * Rename TMPDIR to V4L2TRACERTMPDIR Changes in v2: * Use a temporary directory to store the generated files and remove it afterward.
