Sparse has many warnings like:

on lines on which devpriv->in_buf or devpriv->insn_buf are passed to
le16_to_cpu(). This suggests that both of these variables should actually
be of type __le16.

This is, as usual, compile tested only. I tried to verify as best as I
could that this is a sane change, but I am unable to test on the hardware.

That seems fine. Perhaps the variable 'p' in usbdux_ao_insn_write()
should also be of type '__le16 *'?
