Subject: [PATCH 0/3] dmaengine: stm32: fix reference leak

pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to putting operation will result in a
reference leak here. 

Use pm_runtime_resume_and_get to fix it.

  dmaengine: stm32-dma: fix reference leak in stm32_dma
  dmaengine: stm32-dmamux: fix reference leak in stm32_dmamux
  dmaengine: stm32-mdma: fix reference leak in stm32-mdma
