Subject: [PATCH 10/23] ASoC: hdmi-codec: remove useless initialization

Fix cppcheck warning:

sound/soc/codecs/hdmi-codec.c:745:5: style: Redundant initialization
for 'cf'. The initialized value is overwritten before it is
read. [redundantInitialization]
 cf = dai->playback_dma_data;
    ^
sound/soc/codecs/hdmi-codec.c:738:31: note: cf is initialized
 struct hdmi_codec_daifmt *cf = dai->playback_dma_data;
                              ^
sound/soc/codecs/hdmi-codec.c:745:5: note: cf is overwritten
 cf = dai->playback_dma_data;
