I don't usually interfere, this is your driver to maintain, but this becomes
horribly messy. Have you consider de-hardcoding a little and encapsulate per HW
format details into a C structure ? Drivers these days try to make sure of v4l2-
common library, which as a matter of fact knows that YUV420M and YVU420M have 3
places, so that you don't have to duplicate it in your driver.

Nicolas
