This was introduced by your commit 873bd4 (ASoC: don't set invalid name
string to snd_card->driver field) which means we no longer provide a
driver name for any ASoC cards as they're all relying on using the card
name as the driver name.  We should be doing something like replacing '
' by '_' in the driver name we generate rather than just not generating
a name.

I have to confess I didn't review the patch at the time as it was
applied too quickly after it was mailed out for me to have a chance to
see it.  Sorry about that.
