From 6572c3f2f557034c571ab4cd645bc18646d0b5ce Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 23 Apr 2014 16:07:00 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: remove 'ai_do' from private data This member of the private data is set to the "mode" that the ai command is operating in but nothing uses it. Just remove it.
