[net-next,v2,21/23] net: stmmac: dwmac-visconti: use devm_stmmac_probe_config_dt()

Commit Message

Jisheng Zhang Sept. 16, 2023, 7:58 a.m. UTC

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().
