dmaengine: pch_dma.c: Avoid data race between probe and irq handler

2020-05-20T06:22:06Z

[ 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(). Found by Linux Driver Verification project (linuxtesting.org).

dmaengine: pch_dma: convert callback to helper function

2016-08-08T02:41:40Z

This is in preperation of moving to a callback that provides results to the callback for the transaction. The conversion will maintain current behavior and the driver must convert to new callback mechanism at a later time in order to receive results.
