Subject[PATCH AUTOSEL 4.19 102/205] ASoC: dapm: Avoid uninitialised variable warning
Date
From: Charles Keepax <ckeepax@opensource.cirrus.com>

[ 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.
