Stay tuned... I think these are the patches that need to be picked for this to work/compile: 2c6929d2ea70 dmaengine: s3c24xx-dma: Use vchan_terminate_vdesc() instead of desc_free 3ee7e42f3c9b dmaengine: k3dma: Use vchan_terminate_vdesc() instead of desc_free 397c59bce6cb dmaengine: img-mdc-dma: Use vchan_terminate_vdesc() instead of desc_free 47d71bc75d07 dmaengine: amba-pl08x: Use vchan_terminate_vdesc() instead of desc_free f0dd52c85d61 dmaengine: dma-jz4780: Use vchan_terminate_vdesc() instead of desc_free de92436ac40f dmaengine: bcm2835-dma: Use vchan_terminate_vdesc() instead of desc_free 174334bcd9f8 dmaengine: edma: Use vchan_terminate_vdesc() instead of desc_free b1faf0f564ff dmaengine: omap-dma: Use vchan_terminate_vdesc() instead of desc_free 1c7f072d94e8 dmaengine: virt-dma: Support for race free transfer termination 6af149d2b142 dmaengine: virt-dma: Add helper to free/reuse a descriptor Most probably we missed the 6af149d2b142 and that caused the build failures. - Péter Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
