As for me, that's not a good idea. We'll get massive breakage during
2.6.37 merge window then. Here's example: my sound-related changes to
machine files are merged through Ben's tree, but these changes aren't
in asoc tree, so Jassi is no aware of them, but now these changes are
outdated a bit due to device renaming. And this introduce compile

And if I understood correctly, merging these arch/arm changes through
your tree will result in temporary compile breakage for both trees -
your and asoc.

Keep changes consistent :)
