[ Test Plan ] * Normal certification and kernel regression testing will be run on all GM'd platforms. The failure was catestrophic and was easily caught. [ Where problems could occur ] * Xilinx has changes to the dmaengine driver that have not been upstreamed,: specifically adding support for cyclic dma mode. There is a risk that these non-upstreamed changes have not been tested with this change. [ Other Info ] * BugLink: https://bugs.launchpad.net/bugs/2072456 * Upstream state in original commit was incorrect. * Upstream commit "dma: xilinx_dpdma: Fix locking" Portia Stephens (1): Revert "dmaengine: xilinx: dpdma: Fix race condition in vsync IRQ" drivers/dma/xilinx/xilinx_dpdma.c | 1 - 1 file changed, 1 deletion(-) Acked-by: Kevin Becker Acked-by: Manuel Diewald
