Douglas Anderson e11c7d39fa Revert "i2c: i2c-qcom-geni: Fix DMA transfer race" ... [ Upstream commit 9cb4c67d77 ] This reverts commit 02b9aec592. As talked about in the patch ("soc: qcom: geni: More properly switch to DMA mode"), swapping the order of geni_se_setup_m_cmd() and geni_se_xx_dma_prep() can sometimes cause corrupted transfers. Thus we traded one problem for another. Now that we've debugged the problem further and fixed the geni helper functions to more disable FIFO interrupts when we move to DMA mode we can revert it and end up with (hopefully) zero problems! To be explicit, the patch ("soc: qcom: geni: More properly switch to DMA mode") is a prerequisite for this one.
