When do you expect to send these on so that they end up in linux-next and eventually Linus's tree? Note that it looks like something happened with the commit messages when you applied these. Specifically, the Fixes tags appears to now have a line break in them and there's also some random whitespace before your SoB: Fixes: c3bf8e21 ("drm/msm/dp: Add eDP support via aux_bus") Cc: stable@vger.kernel.org # 5.19 Reviewed-by: Dmitry Baryshkov Signed-off-by: Johan Hovold Tested-by: Kuogee Hsieh Reviewed-by: Kuogee Hsieh Patchwork: https://patchwork.freedesktop.org/patch/502667/ Link: https://lore.kernel.org/r/20220913085320.8577-8-johan+linaro@kernel.org Signed-off-by: Abhinav Kumar's avatarAbhinav Kumar It's possible just the gitlab UI that's messed up, but perhaps you can double check before they hit linux-next, which should complain about this otherwise.
