Subject: [PATCH 2/2] dmaengine: mmp: fix Wvoid-pointer-to-enum-cast warning
Date: Thu, 10 Aug 2023 12:00:00 +0200	[thread overview]
Message-ID: <20230810100000.123515-2-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20230810100000.123515-1-krzysztof.kozlowski@linaro.org>

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

  mmp_tdma.c:649:10: error: cast to smaller integer type 'enum mmp_tdma_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
