Subject: [16/46] dmaengine: ste_dma40: use dmaenginem_async_device_register to simplify the code
Date: Fri,  3 Aug 2018 15:19:46 +0800	[thread overview]
Message-ID: <20180803072016.21544-17-sjhuang@iluvatar.ai> (raw)

Use dmaenginem_async_device_register to simplify the code:
	remove dma_async_device_unregister.
	remove label unregister_slave, unregister_memcpy
