Subject: [PATCH 1/2] dmaengine: pl08x: constify pointer to char in filter function
Date: Thu, 8 Feb 2024 21:27:41 +0100 [thread overview]
Message-ID: <20240208202742.631307-1-krzysztof.kozlowski@linaro.org> (raw)
The opaque argument chan_id passed to filter function is actually
pointer to const memory, so make that obvious in the filter for code
readability and safety.
