Merge tag 'dmaengine-fix-5.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine
Pull dmaengine fixes from Vinod Koul:
"A couple of core fixes and odd driver fixes for dmaengine subsystem:
Core:
- drop ACPI CSRT table reference after using it
- fix of_dma_router_xlate() error handling
Drivers fixes in idxd, at_hdmac, pl330, dw-edma and jz478"
