Subject: [PATCH v2 net-next 08/10] pds_core: Fix up some minor issues
Running xmastree.py against the driver found some
RCT issues, so fix them.
Also, if allocating pdsc->intr_info in pdsc_dev_init()
fails the driver still tries to free pdsc->intr_info.
Fix this by just returning -ENOMEM since there's
nothing to free at this point of failure.
