3 drivers have the same enable function name, ili9163 and hx8357d has
clearly copied from ili9341 which actually supports the yx240qv29 panel.
At least hx8357d managed to update the display mode variable name,
ili9163 didn't. It's not unlikely that I reviewed these drivers...

But that has nothing to do with this patch:
