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