[PATCH 3.16 069/133] regulator: da9063: Return an error code on probe failure

[Ben Hutchings]

3.16.51-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit b6615659827839f3031c6bd4c1599c3c705778ac upstream.

If "regl_pdata->n_regulators == 0" is true then we accidentally return
PTR_ERR(<some_valid_pointer>) instead of an error code.  I've changed it
to return -ENODEV instead.

Fixes: 69ca3e58d178 ("regulator: da9063: Add Dialog DA9063 voltage regulators support.")
