Subject: [PATCH] drm/amdgpu: Remove call to memset after dma_alloc_coherent
Date: Thu, 30 May 2019 23:55:32 +0530 [thread overview]
Message-ID: <20190530182532.GA8370@hari-Inspiron-1545> (raw)
This patch fixes below warning reported by coccicheck
./drivers/gpu/drm/amd/amdgpu/amdgpu_ih.c:63:13-31: WARNING:
dma_alloc_coherent use in ih -> ring already zeroes out memory, so
memset is not needed
