Subject: staging: unisys: unregister netdev when create debugfs fails
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5b12100a53c11ef760e78c2899be8f1bf33812ca;p=linux-beck.git

staging: unisys: unregister netdev when create debugfs fails

Noticed we were not unregistering the netdevice if we failed to
create the debugfs entries. This patch fixes that problem.
