From 82474dade7f4c60206609e7274591d159db105bf Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 23 Jun 2017 11:05:49 +0200 Subject: [PATCH] dmaengine: zynqmp_dma: Remove max len check in zynqmp_dma_prep_memcpy Remove check for "len > ZYNQMP_DMA_MAX_TRANS_LEN" as its not needed. If the length is larger, the transfer is split up into multiple parts with the max descriptor length already.
