After this patch the TD size part of the mediatek quirk can be reduced to maybe a couple lines in total. Yet another version of the Mediatek patcheries will be needed after this, but it will be 50 - 100 lines shorter. This patch is basically just code refactoring, enabling easier quirking. It seems I need to do some rewording of the commit message of this patch as well -Mathias -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
