There are at least run-time dependencies here, although it's possible they're limited to "suspend won't work on Tegra114 unless all those patches are present" rather than "if all these patches aren't present, something other than a new feature will regress due to this series". Mike's certainly been CC'd on the patches many times as quite a few versions of each were posted, and I asked for acks, but got no response. In the past, that's meant he's fine with the patches... -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
