Dan Rosenberg d912e785e2 drivers/video/via/ioctl.c: prevent reading uninitialized stack memory ...

commit b4aaa78f4c upstream.

The VIAFB_GET_INFO device ioctl allows unprivileged users to read 246
bytes of uninitialized stack memory, because the "reserved" member of
the viafb_ioctl_info struct declared on the stack is not altered or
zeroed before being copied back to the user.  This patch takes care of
it.
