Do so, and clarify the comments related to\nversion handling in meson.build.\n\nFixes: d34cefad1791 (\"meson: Fix git version parsing\")\nSigned-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>\n---\n meson.build          | 29 ++++++++++++++++++-----------\n utils/gen-version.sh |  8 ++++++++\n 2 files changed, 26 insertions(+), 11 deletions(-)\n\n\nbase-commit: e39f046f660a6d0954d81b92bd183e7ba679fa56",
