Linus Torvalds a10a019dd4 Merge tag 'dmaengine-fix-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine ...

Pull dmaengine fixes from Vinod Koul:

 - A couple of fixes in core around dma_chan_put() for kref underflow,
   use-after-free and waiting for rcu readers for dma devices

 - mmp sg length and wrong extended DRCMR base for SpacemiT K3

 - hardware buffer descriptor chain fix for xilinx dma

 - sun6i fixes for status behaviour and dma position registers

 - runtime pm reference leak fix for sprd driver
