Dan Rosenberg 4057079855 V4L/DVB: ivtvfb: prevent reading uninitialized stack memory
The FBIOGET_VBLANK device ioctl allows unprivileged users to read 16
bytes of uninitialized stack memory, because the "reserved" member of
the fb_vblank struct declared on the stack is not altered or zeroed
before being copied back to the user.  This patch takes care of it.
