The RTNI field is multiplied by 16 and incremented by 512 before being used as the minimum number of pixel clock per horizontal line, hence it is necessary to subtract those 512 bytes from htotal and then divide the result by 16 before writing the value into the RTNI field. Fix the calculation. Fixes: de2b4917 ("drm/panel/panel-sitronix-st7701: Infer horizontal pixel count from TFT mode") Signed-off-by:
