Subject: [PATCH] drm/tegra: hdmi: probe deferral error reporting
Date:   Fri, 20 Jul 2018 09:55:15 +0200
Message-Id: <20180720075515.26852-1-marcel@ziswiler.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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

Actually report the error code from devm_regulator_get() which may as
well just be a probe deferral.
