From fb8617e1ee4d4057c76730e2f8376ece45663c34 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Fri, 25 May 2018 15:15:09 +0800 Subject: mmc: sdhci-*: Don't emit error msg if sdhci_add_host() fails I noticed below error msg with sdhci-pxav3 on some berlin platforms: [.....] sdhci-pxav3 f7ab0000.sdhci failed to add host It is due to getting related vmmc or vqmmc regulator returns -EPROBE_DEFER. It doesn't matter at all but it's confusing. >From another side, if driver probing fails and the error number isn't -EPROBE_DEFER, the core will tell us something as below: [.....] sdhci-pxav3: probe of f7ab0000.sdhci failed with error -EXX So it's not necessary to emit error msg if sdhci_add_host() fails. And some other sdhci host drivers also have this issue, let's fix them together.
