So that's the problem Andy suggested.
snd_sof_dbg_init() returns an error for whatever reason, and this is
considered as a fatal error and the probe fails.  The error about
debugfs is no fatal error, it should continue.

Moreover, as I mentioned for another patch (I read that before this
one due to the mail delivery order :), it would fail always when
CONFIG_DEBUGFS=n.  At best, create a wrapper for CONFIG_DEBUGFS=n to
return 0 (and void for free).


thanks,

Takashi
