Subject: staging: comedi: icp_multi: remove n_aochan from boardinfo
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fafe91a8b2ea372b76e0cbad995cea8afd77b5da;p=linux-beck.git

staging: comedi: icp_multi: remove n_aochan from boardinfo

There is only one board type supported by this driver and the
number of analog output channels is constant. Remove the
boardinfo for it and just open-code the value.
