| By default, a media driver auto-selects all possible ancillary |
| devices such as tuners, sensors, video encoders/decoders and |
| frontends, that are used by any of the supported devices. |
| |
| 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 |
| are, in fact, necessary will result in the lack of the needed |
| functionality for your device (it may not tune or may not have |
| the needed demodulators). |
