From 061425d933ef9259dbe3789a3a3c63063f53202d Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 23 Jun 2023 12:04:15 +0200 Subject: [PATCH] net: stmmac: dwmac-qco-ethqos: use devm_stmmac_probe_config_dt() Significantly simplify the driver's probe() function by using the devres variant of stmmac_probe_config_dt(). This allows to drop the goto jumps entirely. The remove_new() callback now needs to be switched to stmmac_pltfr_remove_no_dt().
