Subject: [PATCH net-next 07/22] net: stmmac: dwmac-intel-plat: use devm_stmmac_probe_config_dt()
Date:   Tue, 29 Aug 2023 18:40:18 +0800
Message-Id: <20230829104033.955-8-jszhang@kernel.org>
In-Reply-To: <20230829104033.955-1-jszhang@kernel.org>
References: <20230829104033.955-1-jszhang@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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().
