There are also some debug messages displayed through dev_dbg() and netdev_dbg(), that are controlled through CONFIG_DYNAMIC_DEBUG. Any idea whether these should be also enclosed by GDM72XX_DEBUG, or left to be handled separately by CONFIG_DYNAMIC_DEBUG only? The capitals was a slip, thanks for spotting this. I'll submit an updated patch to fix this too. -- 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/
