i2sbus_add_dev() is supposed to return the number of probed devices,
i.e. either 1 or 0. However, i2sbus_add_dev() has one error handling
that returns -ENODEV; this will screw up the accumulation number
counted in the caller, i2sbus_probe().
Fix the return value to 0 and add the comment for better understanding
for readers.
