Subject: staging: comedi: usbduxsigma: rename {send,receive}_dux_commands()
X-Git-Tag: next-20130607~22^2~211
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2bdd6d234acab1d9661e2e2bc2a9ceba11979b9b;p=karo-tx-linux.git

staging: comedi: usbduxsigma: rename {send,receive}_dux_commands()

Rename these functions so they have namespace associated with the
driver.

Also, rename the #defines used for the bulk transfer commands and
move them up with the other defines.
