Subject: [PATCH] ASoC: SOF: align the hw_free sequence with stop
Git-commit: 0b639dcd457b1d3fc660e5a77b02cf65acde3b5a
Patch-mainline: v5.17-rc1
References: jsc#PED-850

Even though the order of stopping the DMA and freeing the widget list is
not important, align the sequence to match with the stop trigger to
avoid confusion.
