I shouldn't have authorship on that patch at all. The original is at https://android.googlesource.com/kernel/tegra/+/fb382752691d74a849996daf77be961ca2cdae97 and I must have screwed up the authorship when fixing conflicts when cherry-picking it to the android-tegra-moto-2.6.39 branch. Please change the author back to "Gary King <gk...@nvidia.com>". -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
