[ Upstream commit fc269c0396448cabe1afd648c0b335669aa347b7 ]
Commit 4a75aae17b2a ("ASoC: dapm: Add support for multi-CODEC CODEC to CODEC links") adds loops that iterate over multiple CODECs in snd_soc_dai_link_event. This also introduced a compiler warning for a potentially uninitialised variable in the case no CODECs are present. This should never be the case as the DAI link must by definition contain at least 1 CODEC however probably best to avoid the compiler warning by initialising ret to zero.
