195 By default, a media driver auto-selects all possible ancillary
196 devices such as tuners, sensors, video encoders/decoders and
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.
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
206 the needed demodulators).
