[ Upstream commit b4e5646178e86665f5caef2894578600f597098a ]

We regularly get dmesg error reports of:
[   18.184066] hdmi-audio-codec hdmi-audio-codec.3.auto: ASoC: error at 
snd_soc_dai_startup on i2s-hifi: -19
[   18.184098]  MAI: soc_pcm_open() failed (-19)

These are generated for any disconnected hdmi interface when pulseaudio
attempts to open the associated ALSA device (numerous times). Each open
generates a kernel error message, generating general log spam.

The error messages all come from _soc_pcm_ret in sound/soc/soc-pcm.c#L39
which suggests returning ENOTSUPP, rather that ENODEV will be quiet.
And indeed it is.
