[ 055/218] staging: comedi: das08: Correct AO output for das08jr-16-ao

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Ian Abbott <abbotti@xxxxxxxxx>

commit 61ed59ed09e6ad2b8395178ea5ad5f653bba08e3 upstream.

Don't zero out bits 15..12 of the data value in `das08jr_ao_winsn()` as
that knobbles the upper three-quarters of the output range for the
'das08jr-16-ao' board.
