Subject: [PATCH 2/2] dmaengine: of: constify of_phandle_args in of_dma_find_controller()
Date: Thu,  8 Feb 2024 21:27:42 +0100	[thread overview]
Message-ID: <20240208202742.631307-2-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20240208202742.631307-1-krzysztof.kozlowski@linaro.org>

of_dma_find_controller() does not modify passed of_phandle_args so the
argument can be made pointer to const for code safety.
