[PATCH AUTOSEL 5.6 130/149] dmaengine: sun4i: use 'linear_mode' in sun4i_dma_prep_dma_cyclic

[Sasha Levin]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ Upstream commit 6ebb827f7aad504ea438d0d2903293bd6f904463 ]

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.
