That patch adds the group names that are used by the debugfs support introduced here. There are a couple of ways to solve this: omit this patch for v4.1 and merge it for v4.2, at which point the dependency will have been merged. That's obviously the simplest one and given that this is debugfs support it isn't very critical, just nice to have. Another possibility would be for you to ack this patch so that I can take it into the same branch as the dependency. The remainder of this series doesn't depend on either of the two patches, so they should be fine for you to take into your tree. Yet another alternative would be for me to provide a stable branch that can be merged into the Tegra and IOMMU trees, but quite frankly I don't think it's worth jumping through hoops like that for this particular patch. I'd prefer either the first or second alternative, whichever suits you best.
