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.

M'boumba Cedric Madianga	aea08a5dfa	dmaengine: stm32-dma: Fix unchecked deference of chan->desc ... 'commit d8b468394f ("dmaengine: Add STM32 DMA driver")' leads to the following Smatch complaint: drivers/dma/stm32-dma.c:562 stm32_dma_issue_pending() error: we previously assumed 'chan->desc' could be null (see line 560) So, this patch fixes the unchecked dereference of chan->desc by returning operation not permitted error when stm32_dma_start_transfer() does not succeed to allocate a virtual channel descriptor.
