regulator_get_optional() can fail for a number of reasons besides probe deferral. It can for example return -ENOMEM if it runs out of memory as it tries to allocate data structures. Propagating only -EPROBE_DEFER is problematic because it results in these legitimately fatal errors being treated as "regulator not specified in DT". What we really want is to ignore the optional regulators only if they have not been specified in DT. regulator_get_optional() returns -ENODEV in this case, so that's the special case that we need to handle. So we propagate all errors, except -ENODEV, so that real failures will still cause the driver to fail probe.
