Subject: [PATCH 1/5] thunderbolt: Remove a meaningless NULL pointer check before dma_pool_destroy
Date: Mon,  1 Oct 2018 12:31:18 +0300	[thread overview]
Message-ID: <20181001093122.65833-2-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20181001093122.65833-1-mika.westerberg@linux.intel.com>

From: zhong jiang <zhongjiang@huawei.com>

dma_pool_destroy() already takes NULL pointer into account so there is
no need to check that again in tb_ctl_free().
