'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

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).
