Subject: [PATCH] dmaengine: idxd: No need to clear memory after a dma_alloc_coherent() call
Date: Fri, 21 Jul 2023 07:35:46 +0000 [thread overview]
Message-ID: <0bd20a5f09b3419e1d4d8c2b6786e886@208suo.com> (raw)
In-Reply-To: <20230721073440.5402-1-xujianghui@cdjrlc.com>
dma_alloc_coherent() already clear the allocated memory, there is no
need
to explicitly call memset().
