If you enter `make menuconfig` for your kernel then you can type slash ('/') to
search for config options. If you search for VIDEO_HELPER_CHIPS_AUTO then you
get output like this:
Location:
-> Device Drivers
-> Multimedia devices
-> Video For Linux (VIDEO_DEV [=n])
-> Video Capture Adapters
which tells you where to find and disable that option.
If you search for VIDEO_WM8775 then in addition to it's Location you also see:
Depends on: VIDEO_DEV && !VIDEO_HELPER_CHIPS_AUTO && VIDEO_V4L2 && I2C &&
EXPERIMENTAL
This tells you that that option is only visible when VIDEO_DEV is enabled,
VIDEO_HELPER_CHIPS_AUTO is disabled (which it isn't), VIDEO_V4L2 is enabled
etc...
So using the search facilities in `make menuconfig` like this you should
be able to find and set correctly these options on your own...
