X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=fc9826dec54c445d1bfbb8fd85d3382dc90bb110;p=openwrt%2Fstaging%2Fblogic.git

dmaengine: ste_dma40: use dmaenginem_async_device_register to simplify the code

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