From 5d55a30c50a3740b415080ce9a9c7b2c642daec7 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 29 Oct 2012 10:06:34 -0700 Subject: [PATCH] staging: comedi: rtd520: remove 'aiChans' and 'aiBits' from boardinfo All the boards supported by this driver have the same number of analog input channels and resolution. Remove the boardinfo for this and just open-code the values in the attach.
