The ASoC platform driver for Mediatek MT8173 registers several components with identical name. This cause an error: "Directory '11220000.audio-controller' with parent 'mtk-rt5650' already present!" when adding debugfs directory for those components. To fix this, the function 'fmt_single_name' can receive the name of the component driver and concatenate it to the name of the debugfs directory for the component.
