Subject: [PATCH 1/2] dmaengine: qcom: fix Wvoid-pointer-to-enum-cast warning
Date: Thu, 10 Aug 2023 11:59:59 +0200	[thread overview]
Message-ID: <20230810100000.123515-1-krzysztof.kozlowski@linaro.org> (raw)

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

  hidma.c:748:8: error: cast to smaller integer type 'enum hidma_cap' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
