Subject: [PATCH v5 5/6] phy: rockchip-pcie: Change to use devm_clk_get_enabled() helper
Date: Mon,  2 Sep 2024 00:02:12 +0530	[thread overview]
Message-ID: <20240901183221.240361-6-linux.amoon@gmail.com> (raw)
In-Reply-To: <20240901183221.240361-1-linux.amoon@gmail.com>

Use devm_clk_get_enabled() instead of devm_clk_get() to make the code
cleaner and avoid calling clk_disable_unprepare(), as this is exactly
what this function does. Use the dev_err_probe() helper to simplify
error handling during probe.
