This option is used only by av7110 and by an USB driver. As the av7110 is the first DVB hardware, hardly found those days, let's opt to place it at usb/Kconfig, as the driver with needs it might have a longer lifetime. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

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.
