If you enter `make menuconfig` for your kernel then you can type slash ('/') to |
| 29 |
search for config options. If you search for VIDEO_HELPER_CHIPS_AUTO then you |
| 30 |
get output like this: |
| 31 |
|
| 32 |
Location: |
| 33 |
-> Device Drivers |
| 34 |
-> Multimedia devices |
| 35 |
-> Video For Linux (VIDEO_DEV [=n]) |
| 36 |
-> Video Capture Adapters |
| 37 |
|
| 38 |
which tells you where to find and disable that option. |
| 39 |
|
| 40 |
If you search for VIDEO_WM8775 then in addition to it's Location you also see: |
| 41 |
|
| 42 |
Depends on: VIDEO_DEV && !VIDEO_HELPER_CHIPS_AUTO && VIDEO_V4L2 && I2C && EXPERIMENTAL |
| 43 |
|
| 44 |
This tells you that that option is only visible when VIDEO_DEV is enabled, |
| 45 |
VIDEO_HELPER_CHIPS_AUTO is disabled (which it isn't), VIDEO_V4L2 is enabled |
| 46 |
etc... |
| 47 |
|
| 48 |
So using the search facilities in `make menuconfig` like this you should |
| 49 |
be able to find and set correctly these options on your own... |
