| This is generally the right thing to do, except when there |
| are strict constraints with regards to the kernel size, |
| like on embedded systems. |
| |
| Use this option with care, as deselecting ancillary drivers which |

| functionality for your device (it may not tune or may not have |
| the needed demodulators). |
