To fix I would suggest being a bit more specific than saying i.MX6. I see UART6 is present on i.MX6UL/i.MX6SX, but not on i.MX6Q/i.MX6DL, so it would be better to specify it in the commit log. imx6ul.dtsi does not have dma nodes under uart6, so I guess you fixed it for imx6sx. > the broken DMA support for UART6, we change the check for event_id0 > to include '0' as a valid id. > > Fixes: 1ec1e82f2510 ("dmaengine: Add Freescale i.MX SDMA support") > Cc: stable@xxxxxxxxxxxxxxx > Signed-off-by: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx> Reviewed-by: Fabio Estevam <festevam@xxxxxxxxx>
