Hello I have a camera that works on two modes: Mono and colour. On color mode it has 3 gains, on mono mode it has 1 gain. When the user sets the output to mono I disable the color controls (and the other way around). Also on color mode the hflip and vflip do not work, therefore I dont show them. I could return -EINVAL, but I rather not show the controls to the user. What would be the proper way to do this? Thanks gain.
