n_sinks and n_sources already tell if a profile consists of an output
and input part.
It's not only *if* but also *what* the input and output parts are.
For now filling in these fields is optional and a routing module
must be able to handle NULL in these fields.

The comment doesn't explain what the names are used for, other than
figuring out whether the profile has inputs and outputs, which is
already available in the n_sinks and n_sources fields. What's the
relation to the name field?
Ok, this could perhaps be explained better; if name is
"output:digital-stereo+input:analog-stereo" then input_name is supposed
to be "analog-stereo" and output_name is supposed to be
"digital-stereo". But the combination of profiles like that is ALSA
specific and this could potentially be used for other backends too, so I
tried to write it in a more generic way.
