Subject: [PATCH 1/2] arm/common/dmabounce : NULL check before dma_pool_destroy
Date: Sat, 29 Dec 2018 13:05:26 +0800 [thread overview]
Message-ID: <1546059926-97458-1-git-send-email-peng.hao2@zte.com.cn> (raw)
NULL check before dma_pool_destroy is unnecessary because
there is a NULL check in dma_pool_destroy.
