From: H Hartley Sweeten Date: Wed, 24 Jul 2013 21:06:38 +0000 (-0700) Subject: staging: comedi: usbdux: rename struct usbduxsub X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=40f1a5ab5e82ab7f15bee23db3db6c3ae957dde4;p=openwrt%2Fstaging%2Fblogic.git staging: comedi: usbdux: rename struct usbduxsub This struct is the comedi_device private data. For aesthetic reasons, rename it to usbdux_private.
