3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 4b6184336ebb5c8dc1eae7f7ab46ee608a748b05 upstream.
The dgnc_mgmt_ioctl() code fails to initialize the 16 _reserved bytes of
struct digi_dinfo after the ->dinfo_nboards member. Add an explicit
memset(0) before filling the structure to avoid the info leak.
