Merge tag 'dmaengine-fix-5.2-rc4' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine fixes from Vinod Koul: - jz4780 transfer fix for acking descriptors early - fsl-qdma: clean registers on error - dw-axi-dmac: null pointer dereference fix - mediatek-cqdma: fix sleeping in atomic context - tegra210-adma: fix bunch os issues like crashing in driver probe, channel FIFO configuration etc. - sprd: Fixes for possible crash on descriptor status, block length overflow. For 2-stage transfer fix incorrect start, configuration and interrupt handling. * tag 'dmaengine-fix-5.2-rc4' of git://git.infradead.org/users/vkoul/slave-dma: dmaengine: sprd: Add interrupt support for 2-stage transfer dmaengine: sprd: Fix the right place to configure 2-stage transfer dmaengine: sprd: Fix block length overflow dmaengine: sprd: Fix the incorrect start for 2-stage destination channels dmaengine: sprd: Add validation of current descriptor in irq handler dmaengine: sprd: Fix the possible crash when getting descriptor status dmaengine: tegra210-adma: Fix spelling dmaengine: tegra210-adma: Fix channel FIFO configuration dmaengine: tegra210-adma: Fix crash during probe dmaengine: mediatek-cqdma: sleeping in atomic context dmaengine: dw-axi-dmac: fix null dereference when pointer first is null dmaengine: fsl-qdma: Add improvement dmaengine: jz4780: Fix transfers being ACKed too soon
