From bfb5eb084ae93eb86d3b088c301500db138963e5 Mon Sep 17 00:00:00 2001 From: Chuhong Yuan Date: Thu, 18 Jul 2019 21:16:09 +0800 Subject: [PATCH] crypto: ccp - Replace dma_pool_alloc + memset with dma_pool_zalloc Use dma_pool_zalloc instead of using dma_pool_alloc to allocate memory and then zeroing it with memset 0. This simplifies the code.
