 194           By default, a media driver auto-selects all possible ancillary
 195           devices such as tuners, sensors, video encoders/decoders and
 196           frontends, that are used by any of the supported devices.
 197
 198           This is generally the right thing to do, except when there
 199           are strict constraints with regards to the kernel size,
 200           like on embedded systems.
 201
 202           Use this option with care, as deselecting ancillary drivers which
 203           are, in fact, necessary will result in the lack of the needed
 204           functionality for your device (it may not tune or may not have
 205           the needed demodulators).
