If there are multiple instances of this codec in a sound card using snd_ctl_new1 will fail with below error because of duplicate control names. snd-sc8280xp sound: control 3:16:0:IEC958 Playback Mask:0 is already present hdmi-audio-codec hdmi-audio-codec.4.auto: ASoC: error at snd_soc_pcm_dai_new on i2s-hifi: -16 Fix this by using snd_soc_cnew along with component name prefix to avoid this duplication.
