It taking too long and timing out is an error condition, so just using a limit value of "100" or something should be perfectly fine. I don't think it's reasonable to put every conceivable nuance into the DT nodes. I'm not applying this patch, sorry. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
