Subject: ASoC: qcom: common: Avoid printing errors for -EPROBE_DEFER
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a63419beafd4edf20761c37dbefd639a0b1b481e;p=linux.git

ASoC: qcom: common: Avoid printing errors for -EPROBE_DEFER

qcom_snd_parse_of() tends to produce lots of error messages during bootup:

	MultiMedia1: error getting cpu dai name

This happens because the DAIs are not probed until the ADSP remoteproc
has booted, which takes a while. Until it is ready, snd_soc_of_get_dai_name()
returns -EDEFER_PROBE to retry probing later. This is perfectly normal,
so cleanup the kernel log a bit by not printing in case of -EPROBE_DEFER.
