[PATCH 2/7] ASoC: codecs: wsa883x: Use designator array initializers for Soundwire ports
Posted by Krzysztof Kozlowski 1 year, 4 months ago
Two arrays (with 'struct sdw_dpn_prop' and 'struct sdw_port_config')
store configuration of Soundwire ports, thus each of their element is
indexed according to the port number (enum wsa_port_ids, e.g.
WSA883X_PORT_DAC).  Except the indexing, they also store port number
offset by one in member 'num'.

Entire code depends on that correlation between array index and port
number, thus make it explicit by using designators.  The code is
functionally the same, but more obvious for reading.
