187	  By default, a media driver auto-selects all possible ancillary
188	  devices such as tuners, sensors, video encoders/decoders and
189	  frontends, that are used by any of the supported devices.
190
191	  This is generally the right thing to do, except when there
192	  are strict constraints with regards to the kernel size,
193	  like on embedded systems.
194
195	  Use this option with care, as deselecting ancillary drivers which
196	  are, in fact, necessary will result in the lack of the needed
197	  functionality for your device (it may not tune or may not have
198	  the needed demodulators).
