From: H Hartley Sweeten Date: Thu, 23 May 2013 19:51:56 +0000 (-0700) Subject: staging: comedi: usbduxsigma: remove 'usbdev' from the private data X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a59a28a32fdfe011ce5045f2a5a207f634d84b2c;p=linux-beck.git staging: comedi: usbduxsigma: remove 'usbdev' from the private data This back pointer to the usb_device is not needed in the private data. Remove it.
