Subject: [PATCHv1 3/3] phy: amlogic: meson8b-usb2: don't log an error on -EPROBE_DEFER
Date: Tue, 13 Jul 2021 05:52:15 +0000	[thread overview]
Message-ID: <20210713055227.1142-4-linux.amoon@gmail.com> (raw)
In-Reply-To: <20210713055227.1142-1-linux.amoon@gmail.com>

devm_phy_create can return -EPROBE_DEFER if the phy-supply is not ready
yet. Silence this warning as the driver framework will re-attempt
registering the PHY. Use dev_err_probe() for phy resources to indicate
the deferral reason when waiting for the resource to come up.
