ALSA: Build jack detection
Since jack detection requires the input subsystem which may not be
desired on small systems it is not built unless required by a driver
that is being built. Drivers using jack detection should use a pattern
like this:
config SND_FOO
tristate "..."
...
select SND_JACK if INPUT=y || INPUT=SND
to ensure that the jack detection API is enabled if the input subsystem
is. If the input subsystem is not enabled then a stub version of the
API is provided.
