Subject: [PATCH] ASoC: mediatek: add missing initialization
Date: Wed, 1 Mar 2023 12:08:35 +0800 [thread overview]
Message-ID: <20230301040835.6322-1-trevor.wu@mediatek.com> (raw)
In etdm dai driver, dai_etdm_parse_of() function is used to parse dts
properties to get parameters. There are two for-loops which are
sepearately for all etdm and etdm input only cases. In etdm in only
loop, dai_id is not initialized, so it keeps the value intiliazed in
another loop.
In the patch, add the missing initialization to fix the unexpected
parsing problem.
