From 14aa4789f0519d0d97f6bf672a077582b08f2cf6 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 5 Aug 2015 10:44:39 -0700 Subject: [PATCH] staging: comedi: me4000: all board types have analog inputs All the boards supported by this driver have analog inputs. They just differ in the number of channels (32 or 16). Always initialize the analog input subdevice in me4000_auto_attach().
