Subject: [PATCH] ASoC: SOF: ipc: ignore DSP replies received when they are not expected
Git-commit: d7a1ed268993f4bc758fa509b22fc730af1623f9
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518

We currently ignore the reply messages from the DSP
when they are not expected but call it out as an error.
Change the error message to a debug message.
