3.6-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ian Abbott <abbo...@mev.co.uk> commit 5d06e3df280bd230e2eadc16372e62818c63e894 upstream. `parse_insn()` is dereferencing the user-space pointer `insn->data` directly when handling the `INSN_INTTRIG` comedi instruction. It shouldn't be using `insn->data` at all; it should be using the separate `data` pointer passed to the function. Fix it.
