Sparse complains:
drivers/dma/stm32-dma.c:957:6: warning: symbol 'stm32_dma_set_config' was
not declared. Should it be static?
SO make stm32_dma_set_config static.

'commit d8b468394fb7 ("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.
