Subject: [PATCH AUTOSEL 5.6 132/149] dmaengine: sun4i: set the linear_mode properly
From: Vinod Koul <vkoul@...nel.org>
[ Upstream commit 8faa77332fe01a681ef3097581a37b82adc1c14b ]
Commit 6ebb827f7aad ("dmaengine: sun4i: use 'linear_mode' in
sun4i_dma_prep_dma_cyclic") updated the condition but introduced a semi
colon this making this statement have no effect, so add the bitwise OR
to fix it"
