Subject: [PATCH 19/46] dmaengine: sprd-dma: use dmaenginem_async_device_register to simplify the code
Date:   Fri,  3 Aug 2018 15:19:49 +0800
Message-Id: <20180803072016.21544-20-sjhuang@iluvatar.ai>

References: <20180803072016.21544-1-sjhuang@iluvatar.ai>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use dmaenginem_async_device_register to simplify the code:
	remove dma_async_device_unregister.
	remove label err_of_register
