Subject: staging: dgnc: remove useless variable 'intr_tx'
X-Git-Tag: v4.9-rc1~119^2~1189
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=262c5e1bab2a8bedb9e5148b17cf6de7674934cf;p=karo-tx-linux.git

staging: dgnc: remove useless variable 'intr_tx'

The 'intr_tx' variable was used only for increasing.
So the 'intr_tx' variable is not useful for this driver.
