From 40642e95850b4425eef1eb74793d28085605ac75 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 27 May 2014 10:30:37 -0700 Subject: [PATCH] staging: comedi: usbdux: remove 'ai_continuous' from private data This member of the private data can be determined from the cmd->stop_src. Do that instead.
