From 6ebb827f7aad504ea438d0d2903293bd6f904463 Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Fri, 7 Feb 2020 10:44:45 +0800 Subject: dmaengine: sun4i: use 'linear_mode' in sun4i_dma_prep_dma_cyclic drivers/dma/sun4i-dma.c: In function sun4i_dma_prep_dma_cyclic: drivers/dma/sun4i-dma.c:672:24: warning: variable linear_mode set but not used [-Wunused-but-set-variable] commit ffc079a4accc ("dmaengine: sun4i: Add support for cyclic requests with dedicated DMA") involved this, explicitly using the value makes the code more readable.
