From eead8c6633669b01f1a5c7b45f64102f2b615864 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 23 May 2013 12:48:12 -0700 Subject: [PATCH] staging: comedi: usbduxsigma: rename the private data struct For aesthetic reasons, rename the struct used for the comedi_device private data from usbduxsub to usbduxsigma_private.
