[PATCH 1/5] ASoC: fsl_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.

[PATCH 2/5] 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.

Considering there is no code being added between them over the
years, I am okay to remove it since it makes things clean. But
as you mentioned, we gotta be careful if code gets added later.

fails.

Looks good.

I would suggest making this patch the first one of the series, since
it is a bug fix and could potentially be applied to stable.

Thanks

[PATCH 5/5] 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.
