ASoC: Ensure we generate a driver name
commit f0e8ed858edb327802ee65fd695cc1538286226f upstream.
Commit 873bd4c (ASoC: Don't set invalid name string to snd_card->driver
field) broke generation of a driver name for all ASoC cards relying on the
automatic generation of one. Fix this by using the old default with spaces
replaced by underscores.
