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

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

199	  This is generally the right thing to do, except when there
200	  are strict constraints with regards to the kernel size,
201	  like on embedded systems.
202
203	  Use this option with care, as deselecting ancillary drivers which
204	  are, in fact, necessary will result in the lack of the needed
205	  functionality for your device (it may not tune or may not have
