PS2, Line 13: static struct soundwire_multilane alc711_multilane = {
            : };
> @Naveen , can you please help here ?

understanding the original query from subrata, since there is a struct alc711_multilane defined, whether config->multilane.lane_mapping default values can be made so that when chip detection fails, it will fallback to those default values.

Actually default should always be SINGLE_LANE, if kernel doesn't get the configurations for "mipi-sdw-lane-%d-mapping" properties.
per soundwire driver team recommendation, there shouldn't be any default values for multi-lane, as it depends on the H/W design.
