Subject: [PATCH AUTOSEL 5.6 130/149] dmaengine: sun4i: use 'linear_mode' in sun4i_dma_prep_dma_cyclic
Date: Sat, 11 Apr 2020 19:03:27 -0400 [thread overview]
Message-ID: <20200411230347.22371-130-sashal@kernel.org> (raw)
In-Reply-To: <20200411230347.22371-1-sashal@kernel.org>
From: YueHaibing <yuehaibing@huawei.com>
[ 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.
