Subject: das08: Correct AO output for das08jr-16-ao
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=d743220d9b53b357f2dbad6ddf83c5a5c9ad18b4;p=comedi.git

das08: Correct AO output for das08jr-16-ao

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.
