Subject: [PATCH 2/2] ASoC: tegra: probe deferral error reporting
Date:   Fri, 20 Jul 2018 10:04:24 +0200

Precedence: bulk

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

Actually report the error codes from of_get_named_gpio() resp.
devm_gpio_request_one() upon trying to get the codec reset resp. sync
GPIOs which may as well just be a probe deferrals.
