Subject: [PATCH] ASoC: soc-core: initialize component list
Git-commit: 8d92bb516831e80fac916701447ee6e9f0a6f0f2
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

It might return without initializing in error case.
In such case, uninitialized variable might be used at error handler.
This patch initializes all necessary variable before return.
