+
+ This menu offers option that will help the Kernel's config
+ system to hide drivers that are out of the scope of the

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