[PATCH v2 2/5] ASoC: imx-sgtl5000: lower log level for potential probe deferral cases

[Stefan Agner]

Not finding the codec/SSI instance can be due to probe deferral.
Do not print error messages in those cases.

[PATCH v2 3/5] ASoC: imx-sgtl5000: don't print EPROBE_DEFER as error

[Stefan Agner]

Probe deferral is to be expected during normal operation, so avoid
printing an error when it is encountered.

[PATCH v2 5/5] ASoC: imx-spdif: don't print EPROBE_DEFER as error

[Stefan Agner]

Probe deferral is to be expected during normal operation, so avoid
printing an error when it is encountered.

Removing the goto would not be strictly necessary. However, if
code gets added later, the cleanup in the EPROBE_DEFER case likely
would get missed.
