Like I said, the code already uses '0' '1' and '2' for the existing codecs so making a change to use #define means patching the code for the other codecs. That is not part of adding WM8998 support and I don't like patches that make unexpected extra side-effect changes that are not relevant to the actual functionality being added by the patch. It's specially annoying when cherry-picking or reverting those patches if they included some extra code change. If we can get this series submitted I can look at making a later patch to improve readbility, but since this really is just a version number I think it would be enough to rename the variable to hpdet_ip_version rather than effectively doing #define TWO 2 > _______________________________________________ > Alsa-devel mailing list > Alsa-devel@alsa-project.org > http://mailman.alsa-project.org/mailman/listinfo/alsa-devel -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
