Subject: [14/46] dmaengine: coh901318: use dmaenginem_async_device_register to simplify the code
Date: Fri, 3 Aug 2018 15:19:44 +0800 [thread overview]
Message-ID: <20180803072016.21544-15-sjhuang@iluvatar.ai> (raw)
Use dmaenginem_async_device_register to simplify the code:
remove dma_async_device_unregister
remove label err_register_of_dma,err_register_memcpy
