dmaengine: fsl-edma: remove redundant assignment to pointer last_sg
The pointer last_sg is being assigned a value at the start of a loop however it is never read and is being re-assigned later on in both brances of an if-statement. The assignment is redundant and can be removed. Cleans up clang scan-build warning: drivers/dma/fsl-edma-common.c:563:3: warning: Value stored to 'last_sg' is never read [deadcode.DeadStores] Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Link: https://lore.kernel.org/r/20220614184759.164379-1-colin.i.king@gmail.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
