| 47 | By default, a media driver auto-selects all possible ancillary |

| 49 | frontends, that are used by any of the supported devices. |

| 51 | This is generally the right thing to do, except when there |
| 52 | are strict constraints with regards to the kernel size, |
| 53 | like on embedded systems. |
| 54 | |
| 55 | Use this option with care, as deselecting ancillary drivers which |
| 56 | are, in fact, necessary will result in the lack of the needed |
