There are some long-time mistakes related to build test drivers, with regards to depends on/select. Also, as we now want to build any test driver without needing to enable anything else, change the logic in order to properly filter them. Please notice that the PCI skeleton is somewhat an exception, as it requires to select *both* SAMPLES and MEDIA_TEST_SUPPORT. I almost changed it to be either one, but decided to keep it as-is, as this is something that we don't really need to be included on any distribution. The only reason for someone to build it is for COMPILE_TEST purposes. 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.
