Hello Mark, Since v4.8 the Samsung snow ASoC driver needs more probe deferrals to wait for all the resources to be available before its probe succeeds. But this makes the error messages printed in the deferral path to do a lot of spam in the kernel log. Slowing the boot process and even making some boot testing to fail due timeouts [0]. This is an RFC series to prevent this to happen by limiting to one-time messages in the case of deferrals. I know you mentioned in the past that the correct fix for this is to have a proper dependency handling and be able to probe in the correct order. But I'm sending as RFC in case you think this can be a workaround to avoid the log spamming, until we have support for that.
