Subject: [PATCH 7/8] ASoC: topology: suppress probe deferral errors
Date:   Wed,  5 Jul 2023 14:30:17 +0200
Message-Id: <20230705123018.30903-8-johan+linaro@kernel.org>
In-Reply-To: <20230705123018.30903-1-johan+linaro@kernel.org>

Suppress probe deferral error messages when loading topologies and
creating frontend links to avoid spamming the logs when a component has
not yet been registered:

    snd-sc8280xp sound: ASoC: adding FE link failed
    snd-sc8280xp sound: ASoC: topology: could not load header: -517

Note that dev_err_probe() is not used as the topology component can be
probed and removed while the underlying platform device remains bound to
its driver.
