> This reverts commit 02b9aec59243c6240fc42884acc958602146ddf6.
>
> 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.

> Fixes: 02b9aec59243 ("i2c: i2c-qcom-geni: Fix DMA transfer race")
