Subject: [PATCH 5/5] dmaengine: mmp: Fix again Wvoid-pointer-to-enum-cast warning
Date: Sun, 25 May 2025 21:26:05 +0200 [thread overview]
Message-ID: <20250525-dma-fixes-v1-5-89d06dac9bcb@linaro.org> (raw)
In-Reply-To: <20250525-dma-fixes-v1-0-89d06dac9bcb@linaro.org>
This was fixed and re-introduced. 'type' is an enum, thus cast of
pointer on 64-bit compile test with W=1 causes:
mmp_tdma.c:644:9: error: cast to smaller integer type 'enum mmp_tdma_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
Fixes: a67ba97dfb30 ("dmaengine: Use device_get_match_data()")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
