Then fix that problem there.  The audio card should not be being created
as a platform device, as that is not what it is.  And even if it was,
the probe should not complete, it should clean up after itself and error
out.

That's not a driver core issue, sounds like a subsystem error handling
issue that needs to be resolved.
