From db4c3eb795696b7f6132d183b1bbe561b54c98c6 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 20 May 2013 14:26:01 -0700 Subject: [PATCH] staging: comedi: vmk80xx: use comedi_to_usb_dev() Use the helper function to get a usb_device pointer from a comedi_device pointer. This removes the need carring the usb_device pointer in the private data.
