The current code of snd_device_name_hint() has a bug when listing up
devices without the device index (e.g. ctl). Because it assigns the
default device index 0 unconditionally and it has a check at the later
point to filter entries with dev >= 0, it ended up with empty
outputs.
The fix is simply to remove the bogus assignment of dev = 0.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
snd_device_name_hint() tries to free the allocated list at the error
path via snd_device_name_free_hint(). But snd_device_name_free_hint()
expects a list terminated by NULL while snd_device_name_hint() doesn't
add it. Adding it may again result in an error and thus isn't
guaranteed to work. Hence we can't add NULL at the error path.
Instead, now the code always allocates one entry more, and zero-clears
the newly allocated beforehand to guarantee the NULL termination.

If the cdev has not been configured explicitly, use the PlaybackCTL
or CaptureCTL value if one of them is set. If neither are set, or if
both are set to different values, then there's no sensible default, so
executing the sequence should fail. The previous code probably tried
to implement this logic, but it was buggy.
Also use more descriptive variable names than "cdev1" and "cdev2".

where "cset-bin-file" is a newly added keyword alongside of "cset",
to indicate cset with binary data in file.
