Subject: [RFCv1 8/8] phy: amlogic: meson8b-usb2: don't log an error on -EPROBE_DEFER
Date: Thu, 17 Jun 2021 19:41:43 +0000	[thread overview]
Message-ID: <20210617194154.2397-9-linux.amoon@gmail.com> (raw)
In-Reply-To: <20210617194154.2397-1-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.
