[PATCH net-next 21/22] net: stmmac: dwmac-visconti: use devm_stmmac_probe_config_dt()

From: Jisheng Zhang
Date: Tue Aug 29 2023 - 06:56:04 EST


Simplify the driver's probe() function by using the devres
variant of stmmac_probe_config_dt().

The calling of stmmac_pltfr_remove() now needs to be switched to
stmmac_pltfr_remove_no_dt().
