I'm afraid that this is going to encourage people to not properly maintain their drivers. The reason why I wanted to call it trivial was because the requirement would have to be that the patches should be small. I lack the knowledge about most SoC drivers to properly review patches that go beyond minor things like cleanup. That said, I guess it would be okay to pick up more complex patches if they had an Acked-by or Reviewed-by from a maintainer. Then again, if they already find the time to review patches it probably wouldn't be a lot more effort to apply them to their own tree. But that's all really speculation, so perhaps it'd be best to just try it out and see how it goes. If it isn't useful we can always drop it again. Thierry
