[alsa-devel] [PATCH v3 10/22] ASoC: Intel: bytcr_rt5651: Not being able to find the codec ACPI-dev is an error

[Hans de Goede]

If we cannot find the codec ACPI-dev, then the snd-soc-core will not be
able to find the codec either and snd_soc_register_card() will just keep
exiting with -EPROBE_DEFER, filling the log with errors each time the
probe gets retried.

Instead simply log an error from the machine driver and exit with -ENODEV.
