Subject: [PATCH v2 18/24] net: stmmac: dwc-qos: Use dev_err_probe() for probe errors handling
Date:   Mon, 8 Feb 2021 16:56:02 +0300

There is a very handy dev_err_probe() method to handle the deferred probe
error number. It reduces the code size and identations, uniforms error
handling, records the defer probe reason, etc. Use it to print the probe
callback error message.
