+Subject: [PATCH] regulator_get_optional: don't print an error when no
+ regulator is found
+
+Only print an error when _regulator_get() is expected to return a valid
+regulator, that is when _regulator_get() is called from regulator_get() and
+we're not using the dummy because we don't have full-constraints, or when
+_regulator_get() is called from regulator_get_exclusive() in which case
+returning a dummy is not allowed.
