Subject: staging: comedi: usbduxsigma: tidy up the usb endpoint defines
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=526f55a9ae583e2459301dc11c01e12599c6f264;p=linux-beck.git

staging: comedi: usbduxsigma: tidy up the usb endpoint defines

Rename the defines so they have namespace associated with the driver.
Tidy up the defines.
