They seem lost in Korea in the end :) Could you catch up if still OK? One of the patches seems slightly conflicting with the latest Linus tree. I can send a rebased one if needed, or you can take it from git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable.git test/fw-direct thanks, Takashi -- 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/
