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through Ben's tree, but these changes aren't in asoc tree, so Jassi is no aware of them, but now these changes are outdated a bit due to device renaming.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 breakage. 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 :) Regards Vasily
