dmaengine: pch_dma.c: Avoid data race between probe and irq handler [ Upstream commit 2e45676a4d33af47259fa186ea039122ce263ba9 ] pd->dma.dev is read in irq handler pd_irq(). However, it is set to pdev->dev after request_irq(). Therefore, set pd->dma.dev to pdev->dev before request_irq() to avoid data race between pch_dma_probe() and pd_irq().
