[PATCH 22/30] staging: comedi: usbdux: rename private data variables
H Hartley Sweeten
hsweeten at visionengravers.com
Thu Jul 25 23:09:48 UTC 2013
The usbdux and usbduxsigma drivers are _very_ similar. For aesthetic
reasons, rename the private data variables in this driver to match
the names in the usbduxsigma driver so we can start sharing the
common code.
