 148           standard. It is used, for example, by automatic firmware updates used

 198           devices such as tuners, sensors, video encoders/decoders and
 199           frontends, that are used by any of the supported devices.

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