Subject: [PATCH net-next] net: mdio: mux-meson-g12a: use __clk_is_enabled to simplify the code
Date: Thu, 26 Jan 2023 21:39:16 +0100	[thread overview]
Message-ID: <84fb199a-d459-646f-8522-0fe1f7455e26@gmail.com> (raw)

By using __clk_is_enabled () we can avoid defining an own variable for
tracking whether enable counter is zero.
