Xi Wang dfd8ee92a9 Staging: comedi: fix integer overflow in do_insnlist_ioctl()
There is a potential integer overflow in do_insnlist_ioctl() if
userspace passes in a large insnlist.n_insns.  The call to kmalloc()
would allocate a small buffer, leading to a memory corruption.

The bug was reported by Dan Carpenter <dan.carpenter@oracle.com>
and Haogang Chen <haogangchen@gmail.com>.  The patch was suggested by
Ian Abbott <abbotti@mev.co.uk> and Lars-Peter Clausen <lars@metafoo.de>.
