Same comment about function signature applies here.

nit: space after override

[klausw, 2016/10/04 23:08:14]

I can't do that. Presubmit insists on me running "git cl format device", and
that deletes the space if I add it.

[klausw, 2016/10/04 23:08:14]

renamed to pose_index.

[dcheng, 2016/10/04 23:19:06]

There's a stray semi-colon, that's why clang-format is misformatting this.
Remove this, and it should be formatted correctly.

Ah, thanks for spotting it. Fixed.
