 164           standard. It is used, for example, by automatic firmware updates used

 213           By default, a media driver auto-selects all possible ancillary
 214           devices such as tuners, sensors, video encoders/decoders and
 215           frontends, that are used by any of the supported devices.
 216
 217           This is generally the right thing to do, except when there
 218           are strict constraints with regards to the kernel size,
 219           like on embedded systems.
 220
 221           Use this option with care, as deselecting ancillary drivers which
 222           are, in fact, necessary will result in the lack of the needed
 223           functionality for your device (it may not tune or may not have
 224           the needed demodulators).
