staging: gpib: fix unset padding field copy back to userspace
[ Upstream commit a739d3b13bff0dfa1aec679d08c7062131a2a425 ]
The introduction of a padding field in the gpib_board_info_ioctl is
showing up as initialized data on the stack frame being copyied back
to userspace in function board_info_ioctl. The simplest fix is to
initialize the entire struct to zero to ensure all unassigned padding
fields are zero'd before being copied back to userspace.
