Couple of things I'd like you to fix in the future:

1. you sent a v2 minutes after v1, with no changelog or reference

(ideally you should include something like:

Changes since v1:
- foo
- bar
- baz

Link to v1: ...)

You can use the b4 tool [1] which makes this really easy for everyone!

2. You overtook the series from your colleague. It's okay, but:

- you should have mentioned this (see point 1)
- it's fine for your colleagues to send your patches, so long as all
of the co-authors AND the person sending add their Signed-off-by tags

Also, check out [2].

Aside from that, this patch looks sane to me.
