Subject: [PATCH 2/7] thermal: rockchip: Simplify clock logic
Date: Mon, 31 Oct 2022 18:50:53 +0100	[thread overview]
Message-ID: <20221031175058.175698-3-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20221031175058.175698-1-sebastian.reichel@collabora.com>

By using devm_clk_get_enabled() the clock acquisition and
enabling can be done in one step with automatic error
handling.
