Subject: [PATCH] crypto: ccp - Replace dma_pool_alloc + memset with dma_pool_zalloc
Date: Thu, 18 Jul 2019 21:16:09 +0800	[thread overview]
Message-ID: <20190718131609.10974-1-hslester96@gmail.com> (raw)

Use dma_pool_zalloc instead of using dma_pool_alloc to allocate
memory and then zeroing it with memset 0.
This simplifies the code.
