dmaengine: stm32-dma: remove unused ‘sfcr’ (1bc4f06c) · Commits · 戴 / test

In stm32_dma_chan_irq(), variable ‘sfcr’ is initialized but never used, which leads to warning with W=1 drivers/dma/stm32-dma.c: In function ‘stm32_dma_chan_irq’: drivers/dma/stm32-dma.c:530:19: warning: variable ‘sfcr’ set but not used [-Wunused-but-set-variable] u32 status, scr, sfcr; So remove it.
