Subject: dmaengine: k3dma: dont use direction for memcpy
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ad7756e7775e1af42ec0032ea0bea968b8f343a7;p=openwrt%2Fstaging%2Fblogic.git

dmaengine: k3dma: dont use direction for memcpy

Memcpy has no direction (copy from memory to memory) so remove the check
in prep_memcpy()
