Subject: [PATCH 3.16 341/346] staging: comedi: ni_mio_common: fix wrong 
 insn_write handler

3.16.39-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Ian Abbott <abbotti@....co.uk>

commit 5ca05345c56cb979e1a25ab6146437002f95cac8 upstream.

For counter subdevices, the `s->insn_write` handler is being set to the
wrong function, `ni_tio_insn_read()`.  It should be
`ni_tio_insn_write()`.

  proper comedi (*insn_write)")
